Hello Sandra Eldridge,

Your title says what kit you prefer... From what little I know about OnStar... "OnStar FMV" appears to be the (SMART) MIRROR
approach... My best recommendation would be to get YOUR
"FMV" from CRUTCHFIELD (see below)...

"PAIN-LESS AND WELL DONE"

I checked ontar.com and your car IS ON-STAR capable...

Sadly I always make things more complex than they need to be:
I don't think the LINCOLN "sound system" is inferior in ANY WAY... and think there has got to be a better solution than by-passing an already REALLY EXCELLENT human interface...
for a "SMART MIRROR" (FMV)... So BEFORE you choose THAT SOLUTION... I would ask you to find out WHAT SERVICES
are presently in your existing MIRROR.

CRUTTHFIELD technicians can do that for you... Phone them... Talk to them...

ELSE take it to your LINCOLN DEALER and ask what service THEY COULD equip in a new car... BECAUSE I can't park without my CAMERAS any more

(just kidding... never scuffed a tire!!).

Years ago CRUTCHFIELD offered a 3-SIXTY-3 solution for my NAVIGATOR... radio navigation system to integrate BLUETOOTH.
I was QUITE DELIGHTED to deal with their technical staff

I have felt the EXTRA SECURITY of knowing the VEHICLE is being tracked... (watched over)... and felt quite secure

I think onstar is a much safer choice than fumbling with your cell-phone trying to use siri while driving.

Hope it all works out well...

Sorry to pose another question while I'm supposed to be offering a solution.
