So my 4.8 reset itself last night...HELP

[X-cellent]

So a few weeks ago I posted about going infor my first service and full software update...upon picking the vehicle up my iPod was acting strange, title of track displayed was in the middle of the entire alphabetical list..no biggie..seemed to have "fixed itself" after a few days...then more strange itmes popped up....

upon start up, stereo goes back to FM..(no channels have been re-programmed so it's just static) no matter what source i have been listening to - happens one out of ten starts...

Seat and steering wheel were not moving back to my memory position..verified in I-drive, but one out of ten times no joy...

This morning, same scenario, no seat movement..FM radio (yesterday was listening to iPod)..pressed seat memory button..moved seat way forway, wheel up and forward......WTF???

Long story short - ALL I DRIVE SETTINGS HAVE BEEN RESET TO INITIAL DEFAULTS!!! Everything on the truck is back to "virgin" settings..no SAT presets, A/C temp setting back to basics, EQ, Treble/Bass, radio, display, manuevering aids...all back to presets like the day I took delivery..oddly, phone still paired in bluetooth...but that was it!

Anyone have an insight before call the dealer and try and explain this...

Today I moved the big red handle to my door and the owners manual out of the glovebox in the event she goes totally deal on me!
