wont accept my lovely new 2gb SD card (Viking). Casio Exilim camera likes it just fine… stereo just says “MMC error”… it has less than 200 files (as per the instructions) and was fresh formatted using the panasonic sd card formatter (usually fixes all sd card related problems)
There’s a rumour that you can format cards in the head unit and thats been know to solve some problems. Don’t know this from experience though, I’d given up and bought an Ipod link cable.
