Customer support ? = Sh#te - Avmap in Italy didn't even respond to email queries or software registration. They are useless
I agree. I found their "support" utterly impenetrable when I looked at this unit, 1-2 years ago when it came out.
They set up a well organised distributor network in the USA and over there it seems to be doing OK. But in Europe it's the usual situation... I would hope that with a handheld this isn't much of a problem, with only occassional database updates required.
However if the reliability is bad that's no good.
Interesting comment about the terrain. It sounds like they have done what Jepp have done in say Flitestar - averaging the terrain out. The
resulting errors are up to 3000ft, mostly in the unsafe direction. Garmin have fixed this on the 496, by using the US shuttle radar data.
All this is unfortunate because the Avmap looks such a nice product. I fly with a yoke mounted G496 (wired up for TAWS, and for a nav backup in case of a total power failure) and frankly wouldn't like to fly with it as my main GPS. The screen is too small. But it does the job, no doubt.
