I'm not sure this is entirely accurate. If I remember from my GPS V manual a complete 'cold' start should take no more than 2 or 3 minutes, maybe 5 maximum. That's for when the unit has been stored or relocated a 'long' way from it's last known position.
[Techie stuff: once the unit can 'hear' one satelite it then knows the time and can look up in it's almanac where that satelite should be at that time. From that it can also work out what other satelites should be in view. Seeing as there are 36 satelites, it's just a case of cycling through those 36 frequencies, which isn't very time consuming.]
I would think a more likely cause to your problem is that the aerial has become disconnected somehow. I guess it's possible that continued vibration will loosen the BNC connection between unit and aerial. Try wiggling the aerial a bit to see if it moves.
Good luck, Iain
