Nah - I have a spanking 6 month old Garmin GPS PilotIII in my flightbag. Amazing piece of kit - much more accurate than the kit in the works motor.
But then I had over 1000 VFR hours logged before I bought it.
Mind you I did get lost on my CPL navex for about 10 minutes - mistook Huntigdon for St Ives as I recall. Happens to everyone.
Cheers
