Service bulletin RSB487

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Riverpark, Inc. has recently discovered an issue with some of their SD cards that may make the dash radio freeze, run slow, and/or reboot. After testing, Riverpark believes that some of the Kingston SD cards were defective from the factory. In response to their findings, Newmar Corporation is issuing TSB 487 to inform dealers and service personnel of the defective parts. Issue: When the SD card plays in the Xite Infotainment Center, it loses communication after a period of time (typically 7-10 minutes). The system becomes sluggish and tries to re-boot continuously. This is partly due to the inability to read the cards information quickly enough, causing the radio?s CPU to ?max out,? resulting in the previously described freezing and rebooting symptoms.
