The unit has started locking up all the time. It will always keep playing music and sometimes I can still change volume or change channels. The screen will freeze on the last image it displayed. I can never load the GPS. Sometimes I get a HDD Error. I think I need to wipe and restore the HDD.

 

I bought the drive off ebay about 1.5 years ago. It was plug and play. What is the easiest way to nuke and reinstall the software so I can get back on the road? I don't care about saving my music but I would like to re-use the same drive.

 

Thanks!
