Hi friends.. Firstly thanks for reading this even if you can't help, I appreciate that. I had a battery go flat on my 635,when I got a new one fitted my idrive controller and buttons don't work. The screen boots up but everything involving the controller and its button is dead.. I can use the CD and pre set FM stations but nothing else. A friend of mine connected a scanning device which came up with code E1CD but I can't find any trace of this anywhere except someone asking the same question related to an idrive but no solutions were given. I've tried the reset holding the volume, power button down and taking the neg lead off the battery but nothing.. If its the idrive then at least I know that, but would there be a way to determine this 100% so I don't rip everything out and the problem is still there..
One thing for sure is that you guys know far more than me so if you have any ideas how I can maybe find out its totally no good or if theres some sort of software reboot trick I can try.. Anyway.. All the best and many thanks for reading..
Jim
