I have been scouring the interwebz and earth to figure out how to get a OEM GM NAV into my Base, Non-Monsoon 06' Grand Prix.... It was pretty simple
1. Purchase the OEM GM NAV Antenna can be found on ebay for $20 GMC GM NAVIGATION ANTENNA GPS ANT MAGNETIC | eBay .... YOU will need this regardless if you want the GPS to work as it also needs it to display the time in your HUD.. pretty much plug and play... just connect it to the back of the nav then stick it under dash.
2. Purchase VSS harness .... This will allow voice commands AND will give the GPS your location and speed etc... Pretty much need it if you want the Navi to work right.. now if you just want the fancy radio and aren't bothered to use the nav function you don't need it. I do not know how to connect this one as I did not care for the Nav function. $54 http://www.ebay.com/itm/NEW-2007-201...item2a1a759e91
3. This step is only needed if you DO NOT have the monsoon sound system.. You WILL need a external AMP to power the unit... the stock one disc player has a built in amp the navigation does not you will need a amp to power it ... You WILL be able to hear the radio but it will be very low until you get a amp.. Now I do not know much about amps etc but I do know I talked to a few people and you can get a small 75watt amp and mount it under the dash and have it wired to the navigation and the speakers for around $150 ( thats what I was quoted) but if your good with car audio i'm sure you can rig it up yourself. If you DO have the monsoon system you should have a AMP connector that is plug and play to the back of the unit. I have found this here .... http://gm-navigation.com/non-bose-amp-system.html it looks like it would work but don't quote me on it just something for you to look into.
4. Finally you will need to get the unit programmed to your VIN as the unit with show LeftLock Activated... Take it to a GM Dealer and tell them you need a "VIN RELEARN" on your OEM Nav... this cost be $85 and about an hour at the dealer.
That is all folks I went through alot to figure all this out so I'm making it easy for you all with a Base GP ... My GP did have OnStar though... Now YOU can just remove your old nav and plug in the new one get the VIN Relearned and install the amp and your set to go if you dont want to use the Nav as we all have GPS on our cellphones anyway. This is the route I went.
PICS!!! You can change the color of the screen from Blue,Green,To a Purplish Color (looks red in the night)
QUESTIONS! JUST ASK ILL ANSWER TO THE BEST OF MY KNOWLEDGE!
