Last night I accidentally left the to down on my e93 and it got rained on.
I let it dry out then started the car and everything worked except the radio.
I could not select am/fm/sat. the i drive would move over to them, but would not select.

I let it sit for another 6 hours and turned it on again and it freaked the hell out. Dash lit up like a Christmas tree, SES came on saying electrical systems malfunction.

I'm not even sure where to start here as far as diagnosing the real problem.

attached is my Carly diagnosis.

Btw, I did have a tpm malfunction error start about a week ago after hitting a pothole. Not sure if related.

reading about similar problems due to RDC but the timing of the rain incident makes me think it might not be that.

I have a kDcan cable but I don't have ista/p so if someone could provide that maybe I can do some better diag?

any help would be appreciated. This is my DD but I'm not really wanting to drive it in its current condition not knowing the root cause..
