6-disk to Navigation swop in 09 LT2

[Towboater1]

I am new to this club and new to Avalanche ownership. I have had my 09 AV about 2 months and love it. It did not come with the navigation unit and I am working towards upgrading from a 6-disk to a Nav unit. I have been reading on this subject for three days and still do not have all of my  questions answered so here goes.

I have a UQ3 radio code and have purchased a 25797978 HU (from an 08 Yukon), VSS wiring harness, GPS antenna. I think I have the install instructions down. My concerns now are, will this HU work? Do I need an amp? And if so what kind of amp to go with the PAC-AOEM-GM1416. Any help is greatly appreciated and information on any other thing I have over looked.

The 25797978 HU is made by Denso instead of Delphi I know the Delphi can be programmed to work with the UQ3/UQ5 (enhanced Speaker System) or the Bose speaker system. I'll check some more Saturday.

Thanks for your responce. Look forward to more information. Does this mean the UQ3 is already amplifyed?

[MS03 2500]

Nope the UQ3 does not have a external AMP you will have to add a amp to the system using the 1416 adapter.

Will the HU I have work? Do you have any recommendations for an amp. The adapter says it is a 4ch is that all I need, any 4ch amp?  Thanks again for your help.

Yes that model will work with the AV, I don't have a recommendation for a AMP. I'm sure someone who has done this will chime in. Good luck with it
