I have a 2011 Honda Pilot Touring model. 2 days ago the radio display was not working properly and some of the radio control buttons stopped working. I disconnected the battery to see if it would "reset" the radio. Now the radio will not turn on at all. It is totally unresponsive. The NAV system is working. The AC controls are working. The radio is dead. I checked the fuses and they are intact. I am original owner and have logged 190k miles. I plan to remove the radio and check connections but I am thinking it need to be replaced. Any thoughts? Thanks.
