Nav radio doesn't work after recall
Hello everyone i own a 2008 Jeep grand cherokee that went in for two recalls the last one that was done was for ignition replacements and two Fobs. when car was returned. I turned on Nav Radio it came on for 5 minutes blinked then went off i took car back 15 min later. dealer had tech remove radio tech told me it was extremely hot. He also said he couldnt understand what happen he new it was working fine because radio was playing before he started working on it. well long story short they came to conclusion that it was a coincidence that it happen while doing recall. but it never had a problem before recall. Now radio has a blank screen with aback light that stays on. once in a blue moon it might come on and work flawlessly for 10 minutes then freeze. Is there anything i can do to get it to work again?
