I was never quite sure why the Garmin 295 lasted such a short time:
Mine's pretty good but they seem to have stopped selling accessories for it:
I tried to get in-car kit a while back with no joy.(Don't need it now though: have a Tom Tom 700 which is the dog's ********)
I did get a Garmin295 Update from website for 29bucks for aviation database though, but I expect these will pack up soon (like Pilot3 updates), forcing pilots to buy a newer model to keep up-to-date and safe.
Cheers
