Please note correction : Garmin Smart Drive 65 incompatible with BC40 camera , use outdated BC30 camera or Garmin Drivetrack 71 which is compatible, Cheers Bax
Model SC430 2008 Have successfully installed Garmin 65 Smart Drive replacing OME Nav & Garmin BC40 back-up camera using two Buck 12volt to 1.5volt converters for power supply in-lieu of changing batteries every 2 to 3 months also hard wiring to power supply through reversing lights helps prevent theft of the camera.
Had to replace the nav unit as up-grade disc un- available for NZ maps The Garmin is the latest version and has lifetime free upgrade. Definition is superior [more pixels ]as is the camera which has 140 degree viewing.
