Audio, Navigation System & Related • 2 questions and sync 2 to 3 vendor?

Hey guys,

So my audio stopped working. I performed the usual - remove fuse/ unplug battery/ Sync update and it still doesn't work. sound does come out when buttons are pressed, voice button pressed, 911 alert not set, etc. but will not produce any music via AM/FM/BT/DVD/ETC. i brought it to the dealer and was told i needed a FCIM replaced.

i was quoted an eye watering $2,232,74 to replace the FCIM.

I called the parts department and was quoted $669 with core exchange.

So my question is, if i upgrade from Sync 2 to 3 - do i need to change out the FCIM?

Any other places to buy the FCIM? ebay has them used for $80 - Ya'll trust them?

For Sync 2 to 3 upgrade, can i buy the non navigation version to save money or must i buy it since i originally have navigation?

Next question, which vendor is do you guys recommend? the prices do vary a couple of hundreds between sellers.
