Hopefully someone can help.  Our maxidas has been stuck on the load screen for a month, have been using our back up.  I thought it would be wise(I was very wrong) to format the SD card and then just update it, but it did not reinstall the basic vehicle options I original had there.  Everything is blank now.  Please help fix my stupidity.  My software update has expired, and I need to update, but just wanted to reinstall what was already on there for now.
