Since I reset my MFD from French to English (that's when I noticed it, anyway) and possibly reset one thing too many, my parking sensors are not working correctly; there is a long beep, and the on/off button blinks. No image appears on the CD player (Stream) screen. I've tried resetting it to factory specs, but to no avail.

I've looked in the Manual, which predictably says, "Take me to your dealer."

Is there anything I should try before I give in obediently and obey? Thanks!

Not sure but there may be a software upgrade for such problems, I had a problem with mine where the sensor display stayed on even when out of reverse, I was told theres a software upgrade for it now.

Could be... It is one of the early models...
