Had similar problem with mine. Couple hours after delivery, presets reverted to originals set at the dealer, could not change channels most of the time, them maybe every once in a while could, occasionally could get a preset to "take" then was gone next time I got in the car...typical electronic malfunctions...no rhyme or reason.
Bottom line...radio had to be replaced. Got the car in Nov. radio was ordered, dely was always 15 days or so out. Finally got tired of the BS in Feb. called SRT, first representative was useless went thru SOS again, after 2 quoted dates were missed contacted another representative at SRT and things started happening...finally.
As it was explained to me, the standard procedure through warranty (even on a brand new vehicle) is that you get a re-manufactured radio and currently there is a nationwide shortage of a particular component... thus the delay. SRT was able to get me a new radio which was good. Left the dealership...radio worked great...dealership said u- connect was taken care of...all I needed to do is pair the phone...WRONG...get an e-mail a few days later to call u-connect and after 2 hours and 3 representatives we got the radio configured to the car and vin. The good news...all is finally well as of last week and I do love these HC's.
I hope it goes better for you...if you have trouble PM me and I will give you the SRT representative that finally got things going for me.
