I was considering the Pioneer AVIC Z1 but man is that spendy. Is there any way to get a factory Nav in my truck and use a different amp other than a Bose system? (in reply to biglg) Post #: 61

When I removed my old radio, there were only 2 plugs. The new nav unit had 4 plugs. I plugged in the two that fit (the two nearest the passanger side when installed), and didn't think twice about the other two (nearest the driver side, closer to the antenna plug). When I took it to the dealer for the "unlock", 2 service guys asked if I hooked up the vehicle speed sensor and other wires. I supposed that is what the other two harnesses are for. Can anyone provide additional feedback on this? The dealer said they can do the unlock, but not program it...? If they just unlock it, will it provide accurate GPS feedback? I had a Pioneer AVIC-N1 that I never connected the vehicle speed sensor wire, and it always worked fine. Just curious to know if I should continue pursuing this and have the radio unlocked, or forget about it. Oh, the dealer said they can wire the vehicle for the speed sensor and other connections. I'm getting a quote on that tomorrow. I'm sure it won't be cheap! Thanks! (in reply to kacyk) Post #: 62

Or an aftermarket one? I was told it was plug and play. The speed sensor is for the automatic volume control I am sure. Raising and lowering the radio volume with the speed. However, I thought it should all be plug and play unless your original factory radio didnt have this feature. Is this an LS model? (in reply to b6876) Post #: 63

Anyone know that? Thanks! Matt (in reply to ZX1100F1) Post #: 65

I took it back to the dealer this morning, and they said no problem. 45 minutes and $80 later, it was unlocked. I picked up an GPS antenna there, $68 (gmpartsdirect.com was on backorder), and just got finihsed installing it. Everything seems to work great! I guess the guy telling me I must have speed sensor wires hooked up was full of it. I believe I found out what the 2 additional plugs on the back of the unit 15882766 are. I believe they are connections for the rear DVD screen. I do not have this, so they are left alone. One problem I am having, I am using a "backed up" DVD nav disc. About every 15 seconds I get a "Map DVD Read Error." Is this common with a DVD map backup disc? (in reply to mkinder) Post #: 66

I know mine is really up to date. I can't find streets that are five years old. Did get my owner's manual insert re: the two free updates on first and second anniversarys. Can't wait.

For the record, I used a different brand DL disc, and it seems to work fine now. (in reply to 73shark) Post #: 69

If Navteq doen't get the updated info they can't make the changes to the DVD's. (in reply to b6876) Post #: 70
