I have a 2013 Ram. Started it up one day and the radio was frozen. The screen just shows the Dodge Logo. The only function that works is the Volume button. The only radio station that works is the last one I had it on. I went to a dodge dealer and was charged $105 Diagnostic fee. They told me it could be and update (which they would run for an additional $105 and it might not work) or I would need a new $2800 radio. This is either a guess (which is not a diagnosis) or a way for them to get another $105 out of me for a common issue. I am about 5,000 miles over the 3 year 36,000 mile warranty. Left the dealer, joined this site and will be calling Chrysler. Any suggestion?
