We've got the exact same problem with a Motorola Droid RAZR M running JellyBean and a new 2013 Ford Escape with Sync/MyFord Touch. Both Pandora and Slacker apps skip tracks every 12 seconds until the number of skips is exhausted. After that, the skip requests continue, but a popup shows up every 12 seconds that states that no more skips are remaining. I had initially contacted Slacker support for help, and they recommended uninstalling/reinstalling, which fixed it for a single car ride. Once we started the car back up and the phone reconnected, the skipping continued. Has anyone found a solution, or is there a definitive root cause that's being tracked in a ticket/bug somewhere? It sounds like it might be an issue with the JellyBean update that was pushed out for the Droid RAZR series phones, based on some of the comments on this thread.
