md 600,
i have tried the av80r in an r44, found it too small to see when mounted on the dash. the slightest vibration makes it even worse -
so i upgraded to the garmin 695 - and the av80r is looking for a new home.
i cant see how you would connect the xrx to the av80r !
there is no mention of it in the manual - nor is there any data socket etc on the unit.
it does have bluetooth - but the xrx doesnt.
