Well my buddy just opened it up and did some thing with a soldering iron, and now the buttons direct me to random ass things; the power button still turns it on however the next track selection for example turns on and off the mx. I called the company that issued the warranty(not the manufacturer) and they said that it seems like it is a malfuntion in the system, and i just have to take it into the place where i had it installed so that they can verify what im saying is true. I asked what model will be replacing it, they told me ill be recieving a 9857, looked it up and it is better than the 9815 because i can hook my ipod up to it without having to but one of those stupid machines, see ya fm transmitter.
Well AVSTANG02 it looks like you sir are the dumbass, if you need the fm transmitter you let me know now
