Bonjour, the micro Sdcard in my 2012 508 has got some bad sectors after my local dealership performed a map update. The result is a unit that reboots every 5 mins. I've been quoted upwards of $1,100 to fix it so am looking at other options. I've been able to take an image of the card and restore it to another sdcard, and I'm just about up and running except for a few files that couldn't be recovered. I'm wondering if anyone out there has a copy of v2.75 firmware that I can use to restore a few files? The exact version on the unit is 2.75.d.2, but anything close would be worth a shot. Any help would be greatly appreciated.
