Hoozyurdaddy -> RE: How to install OEM Nav on 2007 Tahoe (6/15/2008 10:25:39 AM)
|
I need help too, I have a 2008 Yukon, non-Bose truck vin# 1gkfk13058j116441. I have put in a Gm # 25834072 Nav radio, JP Customs VSS wire, GM Nav antenna. I took it to both Behlmann GMC in STL, MO, $67 unlock fee and Bob Brockland GMC in Cahokia, IL $150 labor, and they were able to unlock the theft lock, Nav works great but still no sound, absolutely none, no AC voltage at the speaker outs at all. There is an aftermarket amp installed, and I am M.E.C.P. (mobile electronics certification program) certified in car stereo installation, and have been in this line of work as a master installer for 15 years, so there''s no problems with the amp install. The dealer had called the tech line Friday and they didn''''t even give him the option of calling to get a new vis # , we think that the previous dealer messed up on something regarding the programming. They (GM tech support) even threatened to void any future electrical warranty issues. Any suggestions? Thanks, Brian
