As I dont actually use the App mode on my x3500dab, I thought I would sell the iPod Touch I currently have and switch to a 128gb USB stick I have spare.
Loaded it up with music, plugged it in, built the database and chose to save to memory.
All good and working fine.
But, after stopping and starting the car, the database is lost and you have to re-do the db and save again.
Not really practical.
I've tried a number of drives from 2gb upto a 1tb drive and also tried FAT16, just in case; same problem.
There are quite a few reports of users with the same 'feature' on other forums but I cant find a definitive answer whether this is normal or there is something wrong...
Question then; anybody using a USB drive with their Appradio/x3500/x5500 and dont have to rebuild and save the db after each power cycle?
