2nd Cad Nav in the Av - In & Working! PART 1

[gable74]

No, i get what your saying exactly....thats what i meant when i said that CHEVY doesnt have this style AMP in any of their vehicles, which would stand to reason, they wouldnt have the software available for their TECH2 right?  Like you said before, why pay the money for that software if they never use it, and they would rarely use it because its not an option in ANY chevy vehicle.  What i meant was if i had gone to a Hummer, Cadillac or a GMC dealer, they would probably have the correct software to update the the AMP with because they DO have production vehicles using the NAV and UM8, where chevy does not.  So i believe you are correct in the fact that the tech today probably did everything correctly, but since his software was installing "UC6" as its up-level radio program (because thats the highest level audio you can get in a CHEVY), it wasnt working.  The GMC, Caddy, and Hummer up-level audio program would have been the UM8.  I think thats what you were trying to say before, and i didnt even think about it.  So yes, the AMP is actually just a shell waiting to be programmed, doesnt matter who does it as long as its done with software supporting the UM8 up-level audio.  If i ever need to get a reprogram done again...i sure as hell aint gonna take it to a chevy dealer...its going to GMC, or Cadillac

You are missing it.

they are not buying software just for the amp or hu.

the software package coves say H2, another cover H1, Another covers GTOs, another covers Avalanche only. it has nothing to do with the chevy dealer, the hummer and cad would have the same problem.
you would be where you are now even if you took it to the hummer dealer.


the UM8 does not  get programed for it is no programable and that is why it work when it was install after the theif code was cleared.
if you had a strip modle truck with a cassette deck and put the UC6 in, the UC6 would have to be programed for it to work.

If Iwant the UC6 installed with this amp it would have to be programed togther because they both get programed.

GMC trucks do not have this amp it it or you would have been able to do it. That is the key. no one else makes trucks.


Is your truck a crew cab or ext or reg.

[gable74]

my truck is a 4 door ext. cab.  Sorry, i was getting confused.  So what could they have done to make this work?  You say the problem is my truck, and because its a truck it will never work through programming alone if its inside my vehicle?  What i think your saying is the reason your AV's work is because there is a platform similiar to the AV which is the Cadillac EXT., and they come with the UM8...is that what your saying?  So the only way i can get this to work is like i did originally.....have the AMP programmed in another vehicle platform that supports the UM8, and then transfer the AMP to my truck.  That is essentially what happened with my amp....it was programmed originaly in a Hummer then transfered to my truck.  Am i getting it now?  

[pbuilder]

you almost have

the UM8 has nothing to do with.
this amp is the only amp that will work with the UM8.
this amp is an upgraded amp for thhighend cars, trucks,
the cady, the hummer, denali, have this amp with the UC6 6 disk hu.
This is the problem with your truck. the chevy and gmc trucks do not get this amp.
Since the cady ext got it, we are able to do it. other wise we would be still i think.

the hummer folks can just buy the UM8 and ant. and plug it in and have fun. they require nothing else. they alreadyhave the amp on the bose stock. the poopy amp we got will not go in a hummer for the factory. you get what you are ripped off for when you by a car.
is the ext worth 15k more than an Avalanche. no
have to justify it somehow.

Does this help

[gable74]

yup, now i got it.

the cady, the hummer, denali, have this amp with the UC6 6 disk hu.

didnt realize that, but it makes sense.  They get a much better sound from the UC6 than i do because they have the upgraded system where i do not.

[sperry]

Argh, OK, I'm back..I was wreseling my aux batts this afternoon.

Jimmie; Chevy DOES have a platform that supports the UM8; the only one (so far) in the TrailBlazer.

Scott; If it were the same part #, I'd agree totally; but it isn't. Physically, we see identical Y91 amps, but with those different P/N's, that's the uncertainty I have. When he saw a Hummer with a UC6 as well as another with a UM8.. OK; but the Hummer parts guy told him they only have one amp!

The GMC Sierra Denali has the Y91 amp but NOT the UM8 option; the GMC dealer I was working with said they drop in the INR in anything Denali, and some other models; therefore a close platform. The other's wouldn't work. This was while we were sorting out things, prior to mine working. The Yukon/XL - Denali's have the option.

I believe it's still a mystery until absolute facts are in front of us. We get told one thing from one dealer (tech) and another from another. Folks who read this thread are no doubt disinterested in my speculating and can't get good facts that way. Things worked well for us and we do have a lot of the information correct. Now, we have this problem that's inconvenient and I'm certain it will be resolved with your amp. So we learn that way. GM just isn't much help with the details were chasing or explaining, so let's just wait and see, then discuss it!

[pbuilder]

ok Steve

Rember one thing the amp did work in the truck once the unlock code was done. If it were hummer only it wouldn't have worked..
Rember the problems you had with yours and how simple it was to fix.
GMC make trucks and so does chevy. A trail blazer is not a truck. that is the problem. the Avalanche is as close to a truck as you can get but it still is not a truck. From what I have see the only reason we are able to program ours is because of the Ext.
heres an amp 15054675, does not match anything so far, have any idea if it will work. looks the same.
I know his amp will program in my Avalanche.
no diffrent than your UM8 with one digit off.
All the sudden you believe a parts guy about the amp, but did you believe the rest who told us this mode can't be done.
I am confused, how many time did your installer tell you it cant be done and he couldnt do it.
Have some faith.

the only reason bose made this programable is for the enviroment in which it will be placed in. If these part #s were made for certian models then there would be no need to program them. it could be done by bose and not changed. The above amp I have no idea what it came outof , but I know it will work.

we have the capability of conecting the rear tweeddlers up to our amps but they are not done that way in the ext. The ext should have been made with out the 4 channel output but no it just sit vacant.
Anther reason the are interchangeable.

Just my 2 cents

We have learn alot here and now were almost have 5 working.
a few with 6 disk changers. i believe the xm will plug and play also .


Have you found anyone at any dealer who knew what he was talking about with the upgrades.

me neither.

One reason why i did this install, all to say I have it and it can be done and maybe first to do it which I think I was. At least working

[pbuilder]

Oh

truck and trail blazer are 2 diffrent platforms.
the trail blazer was the first in the chevys to recieve the Um8.
Chevys are the bottom of the GM products.
Like I said its the amp confige that matters, not the HU.
the tahoes might have the Y91 opt. but not sure and still diffrent platform.

[gable74]

Absolutely Scott, i can tell you one thing.....as soon as i get this thing running (and i will cause im so close now) the first thing im going to do is drive back to my dealer and show him just how wrong he was.  The reason being is I have had it working 100% for a a couple of minutes, and with the 6 disk changer to boot.  I know what your saying about the platform issue Scott and the fact that you can program yours thanks to the EXT.  What im still not getting is what exactly is stopping me from getting the correct program into my AMP?  I have the correct AMP and its hooked up correctly, there is communication between the TECH2 and the AMP, why will it not take the program through my truck, but it will through your AV?  What your saying is if i put this AMP back into a hummer, Denali, or Escalade it will program correct, but why?  What is it about the platform of the truck that doesnt let the AMP get programmed correctly?  Is the wiring not the same?  Maybe there is something in the BCM or HU that wont allow them to be programmed together in a C/K truck platform?  Dont get me wrong, I agree with what your saying cause its been proven now in my truck....once the AMP has been programmed in the correct vehicle it will work in my truck, but i cant do the programming THROUGH my truck platform.  On another note...did you get that 6 disk changer i told you about?  That was the same model as mine....so i know it will work perfectly for you.

[pbuilder]

Jimmie

I waited to long on the six disk and someone did a buy now on it. There will be more.

The amp gets a program written for a truck, suv, car for the accoustics of it according to bose. The program sets up the amp for this and that is all it does. Any setup will work in yours or mine, but the cab is the same in your and mine and the EXT so it will sound the way it is supose to sound.

The software package in the tech II for your platform does not have the added amp software in it since it was not an option for the chevy or gmc trucks. that is it  It works in you truck after it is programed because it kind plug and play after the amp is setup. I could have take anybody amp that is doing this and programed it in my Av, put it back in theirs and it would work.  If the amp stays upplug to long it will loose the program. that might be a few week to a month or so I think from pass experience on one.

I have not tried to program the amp yet in my av a tell the scanner that it is a hmmer or denali, but I am going to check that out and see what it does  soon.

[gable74]

well its becoming more and more clear to me now, lets just hope that come tuesday or wednesday i will have mine up and running again.  I will be very anxious to see how you do with my AMP.  Hear anything more about the extra antenna i have?  Do you know anyone looking?  If not im throwing it out on Ebay sometime later today.


A wierd thing happened to me today, i took the truck up to the local car wash today.  This big a$$ 2003 Hummer drove in with 30" wheels and multi monitors mounted to every head rest and about 6 AMPs mounted in the rear.  I asked the guy if he had a NAV HU in that thing and he said yes.  I went over and took a look and it was an aftermarket NAV.  I asked the guy if he still had any of the factory equipment that came in it "LIKE THE AMP!".  He said yes, it was back at his house in a box.  I gave him my number and told him i would buy it from him.  Im still waiting for the phone to ring.

[sperry]

  That would be cool! Better yet if he gave it to you for cheap!
...Or to "test".

Hey Steve

Found some info on the amp outputsof this upgrade amp.
They are rated at 25w in a 4 ohm  oad or 40 in a 2 ohm load.


Which does mean we do have 240w
The sub gets 80w because it is a duel voice coil.
Each door gets 40w and the front tweeters are crossed over.

the EXTs get rear tweeters and the denalis get an added tweedler what ever the hell that is. I think I am going to try to find a part #for them.
the denalis have 40w x 8 =320w
I wonder why the escolade does not get the tweedlers and the denali does.

[sperry]

     I knew it was something like that.. But I thought Bozo liked to use 8 Ohm speakers? (Kinda dumb for auto stereo.  )

  If someone here has an EXT.. to answer this..
  Are these tweeters/twiddelers mounted on the ?pillars? or whatever their called, between the front & rear doors, or way back on the upper sides.

  If they're in the back, and the paneling is ordered, it may have a cutout for the EXT's back-up detector lights...

Thanx, Scott - It may not be a KiloWatt but it sure sounds better, even with the Bozo speakers!

[gable74]

So what is the speaker configuration in the AV's?  You guys are the same as me right?  I have 2 in the front Doors.....2 in the EXT cab Doors and 2 in the very front in the pillars by the windshield (tweeters i guess)......and i guess i have a Sub in the console right?  Is that the way you guys are set up as well?

[gable74]

By the way, i threw that antenna Module up on Ebay.......

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&category=38653&item=2470401679&sspagename=STRK%3AMESSE%3AIT

[pbuilder]

you have the same config

the twiddlers go in the rear pilar of the denali

[pbuilder]

the ext does not have them that i know of.

Hello Guys,
just finished exchange of the Amplifier, drop nav. disk in and drove around and is working fine,Done switching wires ( have Question)
C1 connector for UC6 has wire in B1 Radio mute and B2 RSA Enasig
fot the C1 for Y91 that is were MIC will connect, what did you do with those wires and what they work rear controls in console?
I have appointment for tuesday for programming, any advise what to look for? Will the rear controls work after programming?

Hans

[pbuilder]

back of HU you leave alone. at the amp is where the wires get switched and mic added.
you add the vss on c2 of the hu and that is it.

[sperry]

Hans, the RSA (earphones only) should work before programming the amp; mine did.

[Arrivalblue]

That is how I did it vss wire by HU as you guys told me. Also took the dash top off install antena. The wires I`m talking about are in connectors for amplifier, just as wire diagram I got from you shows. When I did unplug C1 connector from my amp has in B1 Gry/blk and in B2 ppl, those wires I na idea what to do with.

[Arrivalblue]

Steve did you connect the Mic or not jet? I just do not want screw something up. I like to have Mic connected, but shows connection right where are those others wires connected.

[pbuilder]

on the amp b1 b2 spot of c1. tape the wires you took out or put heat shrink on.

[Arrivalblue]

O.K Scott I will do it right now and I will be all ready for tuesday programming. Also funny thing was when I put disc in Nav. System for about 3 miles had problem with East West North South, showing me that I`m driving oposite way then I really was.  Now shows every thing o.k
