AvMap = good experience!
No way to display approach charts (for Europe anyway), so far.
It is a great unit though, I have been using it for a couple of years now, as a knee-pad-unit and it always worked fine. Could not get it to fail, even if I tried to hide the antenna under the dash!
As soon as I am getting to installing the pannel it will be installed in there and it will drive my Tru-Track auto pilot. I do not know how it will perform though.
Did I ever tell that it is a lot cheaper in the USA than it is in Europe? And...... it is even manufactured in Italy, if that matters!
The European Jeppesen-data sucks, but I did get good support from my supplier. He even got me some free Jeppesen updates and a free Software update.
Keep a paper back-up with you at all times. You never know when it may fail, but probably when you least expect it!.
