Trying for Navigation Upgrade for 2003 Envoy


Recommended Posts

I have a 2003 Envoy SLT with Bose and Onstar. No XM radio.

 

I just bought the following on Ebay last night.

 

GM Factory Navigation Part # 15204335

Map disk version 2.0 part # 15105609

Antenna GM Part # 15135178

 

While I'm waiting for this to arrive I was wondering if I will need any other parts to complete this system. I've heard about a few people having sound problems after install. Or is a trip to the dealer for a vin reprogram all I need to do. If worse comes to worse I'm sure I could resell the parts on Ebay.

 

Looked in cargo area behind panel on passenger side for Bose amp. Found it having a part# of 15187195. I'm not familiar with that part number at all. Does anyone know if this is lux or non-lux?

Check your glovebox for option code Y-91; that's the lux amp. There is a picture of this amp in the long Nav thread on page 2 or 3. You really need to read this thread all the way through. If you have the lux amp already it's almost a no brainer with a lux Nav.

I would like to personally all members of this board. Your help has been tremendous and informative.

 

My nav unit arrived yesterday. I installed it immediately using the theftlock bypass method. To my suprise the unit worked perfectly. Only thing I had to do was drive to gmc dealer a few blocks away and pay $50 to remove the theftlock.

 

Only thing I have to do now is remove dash and properly mount gps antenna. I just tossed it behind the radio which I know wasn't right.

 

Once again... Much thanks.
