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

 

new battery, no joy
no fuses found blown

a pistonheads post years ago says same symptoms both times was AUU (ipod, usb, mp3 module)
4G43-37-10950
looks like the cable leads to near the subwoofer
still trying to determine how to get trim panel off and sub out...anyone have instructions?

 

You'll probably need to get yourself a MOST loopback connector. Start with the AUU module and loop it out. If everything else starts working again then you've probably found the problem module. If not, then move to the next module until you find the one that's broken. The AUU is a volvo module, but there seem to be a few aston units on ebay. Just make sure you verify the car wasn't a flood salvage.
