On the advice of our local regular favorite body shop ( 3 teen drivers, don't ask!), I went to;

Website The unit would power up but the tuner and 6 CD changer would not work. He disconnected the battery cable from the negative terminal, waited 10 minutes and reconnected it. The FM1/FM2 band in the tuner and 6 CD changer worked fine, but the AM band was still not working. He suspects the failure of the AM band in the tuner caused a voltage drop and somehow disabled the other features of the infotainment module.
He priced buying a new replacement tuner vs. a salvaged infotainment module. The salvaged infotainment module was cheaper. He installed it in less than hour. $200.00 for the parts and labor.
