just got my '06 MDX back from repairs and battery must have been disconnected for a few days. Radio now requires code. I do have the 5-digit code and entered it but it would not work. Did it several times, checked the serial number just to make sure I had correct code. Now it says"error code E". Short of going to the dealer, anyone have any suggestions?

 

Addendum: Tried the code about an hour later (did nothing different) and it worked. Go figure.

 

Bizzare............
