Hello all. I have performed all maintenance and repairs on our 2007 RDX for many years. A few weeks ago, I disconnected the battery for repair work, but when I reconnected it the radio would not accept the usual unlock code. After repeated attempts and several battery disconnections to reset the number of tries available, I decided to display the serial number of the radio so I could get a verified code from Acura - but the radio has lost its serial number! (see picture).

Anybody have any idea what might be happening? How would the radio lose its own serial number?

Thanks in advance.

 

The GPS and Radio have separate codes on a card

 

I know that, and I have the correct radio code. The radio will not accept the code. It also doesn't seem to "know" it's own serial number.
