Hello all,
Well, I finally finished that radio conversion, and it's working well. (Before I had the amplifier installed, I turned the chimes (in the DIC) to loud, and could barely hear them, I had to turn them to 'normal'. So the Sound level/Volume works like it should, and the chimes do too. Also, the built in 'equalizer' works properly (somehow it didn't have much of an effect without an amp).
I installed the amplifier under the center console tray, on the roll over sensor, for easy access. The harness that comes with the amplifier is pretty long, like 3' - 4', so it pretty much goes anywhere you want, within reason. To do this, you need two harnesses, one is a "conversion" harness, the other one hooks up the amplifier).
So here is what I used, I'll attached pics.
- The GM OEM HDD Navigation Radio (from eBay) GM 22997866 (Denso)
- re-program the radio for your vin (I had OEM-RADIOS do that, they guarantee their work.
- Conversion Harness, (part 6308 from
http://www.oemradios.com/parts.php)
- a GPS antenna (part 6311 from the same site)
- the amplifier with harness. from MVI (gm-navigation.com. They have the 'plug and play' harness (they mention it on
https://www.gm-navigation.com/shop/2007-14-gmc-hard-disk-drive-hdd-factory-navigation-system/ but doesn't show it on their site.
The whole installation is pretty much, "Plug and Play" except for one wire, from the conversion harness, that needs to be spliced in to the speedsensor (VSS)
Once you have all the parts/harnesses and antenna, it is a pretty easy install.
(The only thing left to do, is put a SDD hard drive under the center console tray, with all my music, and plug it into the radio's USB port. (that port can not handle more than one USB device at a time btw)
