I didn't say it's cheaper, but you can find bargain GPS's esp. if they
are last years model... I addd the price of pocket fms to the price of
a suitable PDA the added the GPS antenna and the total came to the
almost the same price as a new $600 Garmin.

Do you need to buy updates for a Garmin too or are they free? From
what I read I can find a PocketPC/phone with built in GPS antenna and
lots of other functions for around 300-400eur, then I could install
PocketFMS for 150eur which is still cheaper than the Garmin. Plus,
with the Garmin you can't email, phone, browse the web, use a calendar
etc. Updating PocketFMS does seem to become expensive over time
though, 15eur/month for database updates and 60eur if a program update
comes. Therefore my question does it cost a lot to update a handheld
GPS such as Garmin or is it a one time fee and free updates for a
lifetime?

What about Jeppesen products? Their site is not very clear about what
you can do with their programs and I couldn't find prices either.
Jeppview, Flitestar, Jeppesen Internet Flight Planner (JIFP),...?

To Andy:
what I want from a GPS on my pda is accurate position, moving map,
flightplan with track line deviation and steering info. So basically a
backup navigation tool.
