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

[sperry]

No, it's just for noise-cancelling. Some don't like "AudioPilot" anyway.

It can be shut off in the audio menus of the HU. Or programmed off(If I remember, it's a default setting) with a Tech II. If left on and enabled without a mic, weird operation could result. (Lower volume mostly) and it may set a DTC code.

[Avialanche]

Ok, thanks for clearing that up about the mic,    in the previous post you said that the four stubbed off wires need to go to the C1 at RSA,  what about the wires that are already there(which are the same colors) as the wires i've spliced from the C1/amp harness to RSA.

[sperry]

They may "harness" to the amp. That was where my presumtion went the wrong direction.

The old amp rear audio passed  through the RSA first. The Lux wiring connects rear seat audio directly to the HU rear Low Lev outputs - Only.

The wiring that's on the RSA now may work, but derived through the amp. I just have to scope it out physically to see how it routes; I just don't remember. However, if it works, just leave it! Mine was rewired and works even if the amp fuse is pulled. (The RSA is powered from the radio fuse.)

Compare the schematics and the new X-ref to better make sense of it, rather than me trying to type out more confusion for you!

Don't believe all of the designated hook-up you see on the prints. There's conflict on the "GM" side as to the connection ID's. One will show one way and the other one... well you can see why there's a problem. The H2 shows the mic wiring polarity and labeling different that other ones, which something else may have a different discrepancy to yet another!

I'll post the H2 Lux prints later, I have to re-Filesize some of them to fit the limits.

[sperry]

OK, I found some other apparent (MS) problems while tracing connector numbering mis-matches.

This one may resolve the weird audio problem!

Check the X-ref document(s) you have. You may notice the arrowed lines skewed. That'll really mess things up! Apparently, while editing, all it takes is a column to skew by a space, and all really messes up! The lines are drawing lines and don't lock to the text body for alignment retension.

Look at the circuit numbers and match them (Fortunately the wire colors help corrections!)
I (again) re-posted the corrected doc (same reply#) and D/L'd/unzipped and checked it. It didn't change. I just hope it doesn't in your Word or Viewer version!

This doc is dated 1-1-05 in the lower right of the page.

I think this may be the culprit,  how do i turn it off,  can't find it in HU menu's,  unless i'm missing a menu that i don't know how to find.                 The RSA and RSE work fine without the four stubbed off wires.          back to sound quality,       could the H2 use different speaker polarity in the amp/wiring vs Chevy/Cad amp/wiring?      cause the speakers sound like the polarity is wrong.       

[Avialanche]

Also,   I have a Diablosport Predator program loaded,  would that affect the amp programming?

[duramaxHD]

Steve (and everyone else who has provided mountains of info to this thread)--- I keep kicking myself for procrastinating in my TNR upgrade but I keep wanting to just wait "one more day" to see what new help 'arrives' here! One question that has been nagging at me: I know H2's have always been equipped with UC6's from when they first came out...but did'nt all the H2's until mid-2004 have the Y91 Lux amp?? I was under the impression that ONLY the nav HU's and the UB1 could talk to the Lux amp...while the UC6 was ONLY happy with a "dumb" amp at the other end. Does this mean that early H2's (2003 to mid 2004) had "super special edition" UC6's that could work with a Y91 amp???

[sperry]

Yes, to the best of my knowledge: A 15179349 Class II UC6 from an `03 H2. And you're correct on the other details also.

H2 wiring, except for the mic wiring polarity, is the same. The arrowed lines were skewed and that last wiring chart may correct it. The one done just prior (and maybe the one before that ) may have been skewed where the lines point incorrectly.

Review it with the others you printed. And MATCH THE CIRCUIT NUMBERS! in case your word version or wordview messes up the pointer lines.!

I wouldn't worry about the mic yet. Check that wiring!
The noise cancelling is in the manual under audio menus if I remember - `dont have it in front of me.
 

[sperry]

I doubt it's causing this. The only quirk I know of is with RSE. You need to pull that fuse to program several items. INCLUDING the amp. Operation should be the same.

I've triple checked the wiring, i always had it right,  except for not having the Class 2 wire spliced from RSA to AMP,    there's nothing in the owners manual about the noise mic in any of the menu's.       Plus i don't think the subs are working,   wiring at C2/Amp is correct.      What fuse are you talking about?             How do i make the HU and Amp reprogram themselves?      Disconnect battery for 10 minutes?     

[sperry]

"Had it right" as in the old X-ref's or as in the Class II amp schematic? If you were double and triple checking against the Old one and the previous one, compare those docs carefully against the 1-1-05 one. Then, if something doesn't match, go back to the truck. Look closely at the arrows; where they were and where they are now (on the latest one).

HU's and amps won't reprogram themselves (Except the HU from new - `reads in the VIN).

Error codes can set and clear, but I hadn't heard of them causing a change in operation.  The engineer's could certailly change that fact if they wanted to.

Page 3-4 Called "Automatic Volume Control" Look for the menu button as in the symbol at the bottom of this post Audio page 2.

"Automatic Volume Control (AVC): With AVC, the
audio system’s volume can adjust automatically to make
up for road and wind noise as you drive. Use the
down arrow screen button to get to the second page of
the Audio menu. Touch the On screen button to turn
this feature on. The volume level should always sound
the same to you as you drive. You may also touch
the Off screen button to turn this feature off."

This is speed-set in the UC6 and UM8 for the "premium" system, and ambient noise in the "Luxury" system.

I am trying to install unit # 15204335 in my 2004 avalanche and would GREATLY appreciate the programming information that you have.  Thanks!

[sperry]

gdrews35!

There are procedures how to have this done, a few pages earlier in this topic.

Realize that the 4335 HU will not just plug into your Av. You will need a Luxury ClassII amp and rewiring at the amp's connectors.

Amps range in the low $300 area at a cost + 10% store. Try one of our site-supporting dealers and retailers if you don't already have the amp.

I presume you have the DVD & GPS antenna.

The amp MAY require reprogramming and your head unit will need the theftlock cleared. Both can be done in one visit to a dealer, if you follow through with the wiring changes found here.

The older posts discuss more of the findings starting almost a year ago.. Then it's more info and procedure based later on.

Give yourself some time and read through this "Technical novel" and we'll revisit with the Q&A!

Enjoy!

[Avialanche]

All wiring is correct, AVC is off,  no difference,  so i guess i'll have to get it reprogrammed,   can barely hear the Onstar & XM compared to radio and CD,   i noticed in the schematics that Luxury HU(EXT) use a Special Composite  AM/FM antenna system, instead of the mast antenna the premium system uses,  cause radio reception is poor compared to the UC6 HU.         I got this package from JP Customs,  would i just be better off getting a different LUX AMP or HU?         Cause i read on here somewhere that someone else had the same bad audio problem and went to dealer to get amp programmed to the vehicle and ended up with the amp not working at all after the programming,  so i'm concerned that  i probably wouldn't be able to return my LUX amp for exchange/refund to JP customs if Chevy dealer Tech 2 programming makes the amp not work at all.

[midwest kid]

Sperry, would you happen to know what the "FM Composite Signal" is for? I dont have one in the vehicle im trying to integrate this into.

Jason will stand behind the product, but I thought he supplied an adapter harness for the amp? If your wiring is indeed correct, just program it. They can pull document 1129839 or you can cut & paste from here. If the sub'd platform type (Escalade EXT) won't work, use the H2. It only programs the amp and RSA and they use the same.

Remember to remove your RSE fuse prior.

[sperry]

The (Diversity) antenna system is used in the Lux Suv's only. It's the vehicle, not the audio system type that apparently defines the use, but it just happens to end up as the luxury. The combiner-preamp could be retrofit to an av, but you need to set them up physically similar to the SUV's, as this system was set up in a lab.

Back to the amp... Call Jason first, he'll work something out. I thought you pieced this together all this time!

[sperry]

GM terminology depicts it as mentioned in the above reply's.

The diversity reception application is similar to that of a wireless mic receiver, commonly used in music and broadcast industries.

The device may improve reception slightly and maybe a few less "holes" in the FM reception. But it doesn't have to be utilized. Just use a 31" single antenna.

[Avialanche]

I waited two months for jason to get the conversion harness out, in the end jason's supplier/manufacturer couldn't make a conversion harness in bulk for the swap's, so i ended up just buying the lux package and doing the connector changes myself.       About the Antenna,   your're saying the mast antenna is 100% compatible with lux hu.      Does programming with Tech 2 select which antenna setup the hu is to be configured for?

[sperry]

OK, He has a lot of unfilled promises by his vendors... Always a hitch in the get-along..  Talk to him about the dilemma first, however.

The broadcast antenna type is only a hardware concern.. And not for Av's. If it's a Lux SUV, the antennas are in the windows.

Here's GM's description:

The diversity antenna system is comprised of 3 glass mounted antennas, a radio antenna module, and an FM impedance matching module. The primary AM and FM antennas are an integral part of the left rear quarter glass and are connected to the radio antenna module. The secondary FM antenna is an integral part of the right rear quarter glass and is connected to the FM impedance matching module. The radio antenna module processes the antenna reception signals and phase aligns them to create one strong signal. The FM impedance matching module boosts the secondary antenna signal and transmits it to the radio antenna module.

  I C,    Ok thanks for your help with all of this,  will talk to jason tommorrow about what to do next.                        Happy New Year!

Don't give up, good luck!

Happy New Year to all and thanks to everybody that posted in this forum and a special thanks to you Sperry for your help, I now have a TNR installed in my 2004 Escalade ESV (build date 11/12/2003). After disassembling the dash I found that I did have the DK GRN/WHT wire already installed in the radio connector  C2 “E”, but I stilled “Ohm it” to the cluster A4 to be sure. After I installed everything, I reconnected the battery, turned the key to Acc and received the Delphi screen followed by the Cadillac logo. After checking radio function, I inserted Nav disc and in under a minute had my position. After reassembling everything and starting engine “Theftlock” appeared, so a trip to the dealer was scheduled. On Thursday I arrived at the Buick Dealer. They had done work on my Lesabre and assured me that they could clear the Theftlock. The service manger (nice guy) tells the service tech that he has to call GM to get the code to clear the Theftlock. I tell them that they just need to hook up the Tech II to clear the VIN. I then produce the instructions (Thanks Klaus). The service tech then hooked up the Tech II (supervised by the service manager) and in under a minute I was good to go (Did not pull the RSE fuse). After asking the service manager what I owed “NOTHING” just take care of service tech ($20)  the service tech began asking me a load of questions since he has a Envoy and would like to install a Nav unit. I told him to go to the best source on the Net, The Chevyavalanchefanclub.com. Again thanks to everybody for their posts and to you Sperry for your help. Next project will be back-up camera and I am sure I will find what I need to know somewhere on this site. Pictures to follow.
