I got mine off of ebay from this guy.
http://www.ebay.com/itm/200953571594...84.m1436.l2649
I was able to get it for $20, looks like its $25 now. I think there might be people on here that make them from time to time. I was going to make my own, but by the time I got the required pieces and cable, i was going to be at least $15 so I just bought one pre made.
I haven't done the digital speedo/true speed or the unlocking after pushing the engine stop button, but I have done:
- Brake Force Display
- Rear Fog Lights
- Open / Close Windows & Moonroof and Fold Mirrors with key FOB or confort access
- Cell Phone ringtone in car
- Tire Pressure and Temperature in TPMS screen
- Changed iDrive Startup Animation
- M Performace Logo on Dash
- Digital Speed in Instrument Cluster
- Window Auto-Up with Door Open
- Enable Fog Lights with High Beams
- DVD in Motion
- Disabled Seat Belt Reminders
- Removed iDrive / Nav Disclaimers
Always looking for more things to code
