last week bovee said "unreadable". new one same thing. listen to AM/FM for a few days. then nav wouldn't try to lift, no motor noise, nada. then next day no AM/FM, no display, no sound. hands free phone still plays thru speakers. checked fuses 43, 56, 64, 65, 66 all good. any ideas?

 

Simple things first. Make sure the chassis ground is still solid.

 

See if the battery is good.

 

Cheek MOST fiber connection, resourcing at Nav Unit... this happened to me about 5 or six years ago

 

i found a few posts for this same problem on here and Pistonheads indicating:
battery
MOST (usually a bad module of some type)
fuse

i will replace the battery since i really don't know its age and examine the grounds in that area while there.
and see what AMDS tells me
i will report back

i appreciate the quick replys
