Mein Auto: 2007 E92 335i
iDrive Launches only after reset, any suggestions?

I have a E92 335i with iDrive issues still. My iDrive failed recently by not being able to to turn on at all. I had to replace the screen as well as the DVD drive unit as well. When I got the car back the iDrive failed to start and so did the car. They told me that when the system detects low voltage it would fail to initialize. So after realizing the battery was bad I replaced it with an AGM battery, got it registered and programmed, the iDrive still fails to launch. The only way that it will launch is if I pull the fuse and reinstall it or by holding down the eject buttons with the volume button. Both will reset the unit and it will then launch. Now I am trying to trouble shoot it.

My battery reads 12.6-12.7 volts with the car off. I have the iDrive pro with Logic7. Are there any other fuses that could be causing this or a loose connection somewhere that it will tell my iDrive to not start when the car starts? Any help would be nice since I just dumped $2k down and Im still not operating as normal yet. Thanks in advance for all those that can help troubleshoot this.
