* Navman R300 ...
SAVE YOUR MONEY!!!! Mine worked ok first few times then wouldn't display correctly; it would also turn off on its own. Just not worth your money. Only will give a lot of frustration.

Not worth it
Well, it was good for about 5 weeks after that it just died. No battery replacement would bring this baby back to life. At least I got to keep the arm band.
Save your money.

Poor performer
I bought this unit to track how far I travel while walking. The
first unit received had bad segments in the LCD. Amazon
quickly sent another unit that did appear to work.
This unit takes a long time to find sattelites. Several times
it never found ANY, under clear blue sky. It just turned off
after 10 minutes. It would lose signal frequently.
The deal breaker is that when it loses sattelites, it will not account
for distance during the lost signal. Lets say you are walking/running, and the unit is logging distance. For a 10th of a mile, it loses
sattelite. When it gets sattelite back, it starts logging
again from the new point. But it does NOT add the distance
you traveled while the signal was missing. As if I teleported
to the new location. Useless.
