I just bought a 2004 base Deville with comfort convenience package. I was wondering if a can get the gps installed on my non-bose system. Or if its possible to add the night vision system. I can't seem to find either of these items on the internet or even the part numbers. Does anyone know if i can upgrade my base Deville with some more bells and whistles??????

 

Hey Dave,
I own a 04 base Deville as well. Had it for about a year now.
What comes with the comfort and covenience pkg?
I don't have a gps, but wouldn't be better to keep the gps portable?
Also, I heaven't heard anyone really rave over night vision.

Anyway, enjoy your new ride, mine has been great!

To be honest. You are better off buying the aftermarket double din or single din cd/dvd/am/fm/ipod set up.
If you have the bose system then you need a factory amplifier bypass harness. Metra & pac carry this. It keeps your complete bose system working with an aftermarket radio. If you have steering wheel control, pay for onstar you need another module. You need a installation kit also.If you have the door chime you need module cause the door chime s built into the stock radio. If you do not care about the door chime, onstar, steering contol then dont get the modules.

The aftermarket radio can do 15 x more cool stuff than the store am/fm/cd/navigation.
You will not spend much more either.
