Morning Dave,
I initially went down this route but the screen isn't compatible with my car so I'm sending it back. I totally understand your reasoning for taking this route though with BMW charging such hefty sums just to diagnose a small but irritating problem. I would have liked to have kept my car oem but if the Bluetooth is going to be a constant bother then I'm going to have to have a rethink.
Which android screen did you fit if you don't mind me asking?
Thanks for your reply mate,
Wayne
