The iDrive in my 2006 530xi doesn't work. The parts are apparently discontinued. I am considering putting a tablet in my car and connecting it to the ODB2 port to get vital car info. Is anyone familiar with this? What ODB2 app is the best to use and, will I be able to monitor fluid levels, water temp, oil pressure, etc.? Is there car related info available on the iDrive that I won't be able to see from the ODB2 connected tablet? Thanks!
