12V power cable
Consider yourself lucky that Delorme doesn't make the 12V cable any more. They pretty much suck. I've had 2 of them for my PN-40 and both have failed; repaired one and it failed again. They are NOT robust in my opinion, failing in the gps side connector. This, combined with the small screen, my aging eyes, and short battery life have driven me to a Montana which should be here soon! Additionally, if I used AA batteries (even 8X lithiums), the batteries would be killed in about 2 days of the unit being off. Had to just leave it during non-use times with the batteries out. Unacceptable.
