I too an unhappy with the oztopo maps on my 650t.
It becomes virtually impossible to look for any detailed tracks unless
zoomed right in. When planning long trips through the outback this
makes it very hard to know where any track is going to end up.....
Very frustrating - and I think I spent way more than $690.00
I'd love to learn how to create my routes on my desktop
and then download them onto my GPS.....
(or perhaps even drive my GPS from my desktop using my enormous
and easy to read monitor),
Is this even possible? I've never had a gps before.
