Fm Amplifier - Need New One! Help!

[puters123]

Hi there,

I have a 2002 BMW X5 4.4 with Nav and DSP. My FM Amplifier (I believe thats what you call it) has gone belly up. I had some water leakage (one of those big water bottles got a leak) in my trunk, and it spilled down into the spare tire well and destroyed the FM Amplifier. I have no FM now! It is that little box that sits in the wheel well, in front of the spare tire. I took all the numbers off the unit:

BMW BUSINESS BM 53
65.12-6 904 213 AI: 03
BE652715008116
Made by Becker?

Question is now: where can I find a new/used one, and how much I am I looking at for it? Please help, I searched the internet and couldnt really find any information on this. I need my FM Radio back!

Thanks everyone for your help
