I purchased a Garmin Dezl Cam last summer before a trip to Glacier Nat. park and really was impressed with it. Pricey yea, but had I had it a couple years ago it would have precluded litigation in a law suit. My old indash gps had crapped out and needed a new one anyway. Fabricated a mount at peak of the dash where it can be reached from my seat. Pro,s are size, magnetic mount (get it near the mount and it sucks it in) voice command, accelerometor saving footage in case of an accident and telling you what lane to be in. Con's, short battery life. Liked it so much when my old gps died for my car bought a Nuvicam for it. Just piece of mind IMHO. Hope this helps, any questions PM me.
