2 Software Update Questions

The dealer needs to perform a software update to my car related to recall # 10ea02 for the HDP/ HPFP, in order to complete registration through DMV (CA).

1) Car has aftermarket radio, dealer says I need to install a stock radio to perform software update. Does the part number of the radio have to exactly match up in order for the update to go through? Or can I use a radio that fits form other model years/ versions of the 3 series?

2) If the car has an upgraded software for the DME installed, will this cause problems when the dealer updates the car?

I could really use the help as I'm stuck until I get the update taken care of

Thanks,

You'll need to install a radio that was originally sold for your model years. Check RealOEM for a list of part numbers, just punch in your VIN and browse the radio parts.

By upgraded DME software, I suspect you mean a tuned DME. The dealers software update will wipe out your custom tune and you'll have to have your tuner reload it.
