Hi Andy,
I use the wayfinder as well as the braille note gps. I purchased the
wayfinder and installed it on my nokia 7610 and must say the bluetooth
receivers are very good. no wires but the battery life is not as good so I
got another receiver.
it is the fortuna clipp-on which is very good indeed.
the reason for wayfinder is that I am not sure how long gps will be before
it is available on the six point one on the braille note.
for me gps is a must.
one thing with not having mainstream is things take time to catch up
e.g. the pk not having the ability to have html emails.
we are lucky though with such grate products as the braille note and the pk.
I am sure things will get there.
