I'm wondering if anyone has experiences like mine concerning the USB connection in console. My WK2 has the lower line radio (non touch screen) with U-Connect. If I plug a MP3 device into it, it will show that it is charging, but the radio will not see it. If I plug a thumb drive into the USB, it will play for a bit, then freeze up. I have tried doing the streaming bluetooth from my smartphone, but it jumps around and is unusable. My MP3 is not ipod. I know I can plug into the jack on the front of the radio, but was hopping to have a better solution. Any ideas? Thanks for any input.
