Hmm. Interested to know what limitations it might have. Can you check Aux In, and visuals in Aux In ?

As I said earlier in the post, everything would be fine until you select the Aux in (I didn't have a tuner at the time but I'd imagine it would do the same) the player would then lock and it couldn't restart. This was nearly 2 years ago, the unit went back for repair and came back with a different serial number.
