I have a 07 F150 with the factory 6 disc changer HU. Today the Sirius radio started updating and continued to update over and over again for 30 min. Then it played for 30 min then started doing the update again. Once it completed the update 4 times the radio displays an error: Bad String and will not play anymore. If I leave it on it will update again then show the Bad String error again. Has anyone seen this before?

 

While in satellite mode, press Aux and Preset 2 at the same time to pull any trouble codes.

 

Thanks, I'll try that tonight.
