I had mine in my Z4MC, swapped it for an E39 M5 in July. Moved it to the M5. On the drive home from Cincy, it was skipping like crazy (which it had been doing in the other car too, though I didn't remember it being so bad). When I got back home, I tried the easiest fix - swap out the SD card. Voila. That was the problem, other card was bad. Works like a champ now.
You'll like it. Great device. Mine was delivered quickly by same vendor you ordered from. You'll like it!
