I want to buy NON working BM53 radio modules

[740iL]

Like i said above, if i can get a few NON working i can get the newest radio module for about $400 so i need a few for the core charge. Also I'm i the middle of the proseses of opening my own online BMW part store.
Just some of the prices.
Can you guys tell me the BEST OEM upgrades for the X5 all years. Audio, video, lighting, outside, inside and ect. If you guys on this board have a little time, just please tell me what you think are the OEM upgrades to do to your X5's. Also i have a wholesale account with my local BMW dealership and they give me GREAT prices, so i will post some of the prices

Bluetooth $650 ALL parts
OEM latest video module with all the OEM parts $1099
Exchanged BM53 radio modules $400

I will post more soon.

Thank you for your time.
