Hey I had a Z2 stolen and I just got a new one and I had the XM, iPod, backup cam and bluetooth installed as well as an amp. Some of the wires were cut some were just unplugged. A guy at an audio install shop told me that if they cut the wires so the add ons like the iPod adapter, I would need to buy an all new iPod adapter, and a new plug couldnt just be crimped of soldered on. Any truth to that? Any advice?
