My stereo keeps stopping while playing music from a USB stick. It then reads 'Reading USB' and after about 30 seconds says 'read Error' and the radio comes on. I removed it and the next day put it back in and worked for about 20 minutes then did it again on a different music folder?Anybody else had this? I'm going to try another USB stick but this one is a new Sandisc that works fine in other equipment.
