Hi , I have 2009 Honda accord touring with sat nav . I had to disconnect battery , and now i need to enter sec code. I looked for it in all possible locations - glove box etc . After ringing local dealer i was instructed to hold down 1 and 5 on radio keyboard , turn on ignition and radio identification code should come up on screen ( i need radio identification number and VIN so they could generate my sec code ) .. But all i'm getting is error code. after checking net/youtube i think it works on 7th Generation Honda's . Any advise ?
