Hi, I can help you with this. Sorry for your trouble....
Has the battery gone dead recently? Needed a jump?
The one thing you can try is to "reboot " the system.....like a PC
disconnect the battery if you are able , and wait 15 minutes or so and then reattach it and retry.
If that doesnt fix it, then it will need to be removed, checked for proper connection,and if its ok, sent out for repair.
Ok, thats one way, but your Pilot can display the serial number electronically.
This will only work after the memory is cleared by a battery disconnect.
Hold down the 1 and 6 radio station preset buttons with the radio off.While holding them , turn the radio power on. It will show the numbers and I can get the code with them
Inform me of the results....
Yes, Honda has tightened the purse strings a bit, but if you are under 75k
they may chip in for half of the repair. Have your dealer contact the rep. in your area and see if they will.
The normal cost is around 300 nplus the r&r time of the unit. Should be an hour labor
