Both Nav4All and Amaze are both very good when used on my SE K800i with a separate GPS. Prefer Nav4All and on a recent round trip to Manchester & back (total 100 miles), it made no mistakes, reminded me when speeding and download costs via O2 were zero. Just use direction arrows, not maps.
Good free fun!
