OK, and now TODAY the "pause" button, instead of not doing anything, now all of a sudden started acting as the "band" button and switches from fm1, fm2, fm3 and am. The band button still does nothing. I plugged my N1 brain back in, and the pause and band buttons work normally. Unplugged the N1 and re-installed the N3 and still operating abnormally. Does anyone have anything they can help me with? Im sure there are some people with an N1 headunit and an N3 brain. Did this happen to anyone else or will a disc upgrade fix it????
