Just another saga on this quest for upgrades. I purchased a complete second Nav Radio with the exact same part number that was said to be unlocked for $255 out of a 2013 Yukon. I received it and took my Nav radio out and plugged in the second radio. It said LOCKED on the screen so I took it back out and put my first Nav radio back in. When I did that the Radio no longer has a signal and the radio part quit working. I checked the antenna from the back of the radio and it did not help. I unplugged the antenna adapter to the original antenna wire and that did not help. I took them both apart a second time and checked for bent pins or anything of the sort and found nothing yet the radio still had no reception. The Nav works, the CD player works, the DVD player works, the Clock works, the GPS works but no radio in either AM or FM? I got frustrated thinking that possibly this second radio had shorted something out when I put it in so I took out the first Nav radio and put my stock original radio back in. Everything worked perfect but it was all laying on the console. I turned it off and put it back in the dash and then turned it back on and nothing! I was livid at this point but I pulled it back out and when I grabbed it to pull it out it turned on? I pulled it out and reached in and pushed and pulled on the wiring and it went on and off. I then disconnected the wiring to the amp for the Nav radio and pulled and pushed on the wires and it never turned off again. Possibly I have a wiring issue with the AMP that has been causing these issues all along????? I have now driven the truck for three days with the stock radio and nothing else hooked up and it works perfectly.
Given all that I just told you what would you do next? Would you send the second radio to Matt and get it programmed for the Tahoe or would you see about having the first Nav radio tested and or repaired and would you be like me and be ready to give up at this point? I am frustrated and need a calm head to help me figure this out rationally so I hope you can help me? PLEASE!
