I received my Holux GPSlim 236 from buygpsnow.com today.
It is much smaller than I imagined it would be! Just slightly thicker than the Pearl and half it's height.
Pairing took about 5 seconds altogether (very easy) the GPS pair code is 0000.
Launched BBmaps and hit "start GPS", it asked what bluetooth source I wanted to use, selected the Holux, and a few seconds later it had my location centered on the map.
The map does rotate to show your direction of travel as "up" on the screen by default, and it does so in small increments, not 90 degree turns, which is nice. By pressing the zero key on the Pearl it brings up a bar that displays the current compass heading and MPH on the lower third of the display.
This section also shows which road you are currently on by name, and when approaching intersections will attempt to display what roads we are "coming up on".
I have to say attempt though because even with a full signal EDGE connection, when there are many streets "coming up", ie: city driving, it cant seem to keep up, often changing to "coming up on Knox St" after I just passed it (at 25 MPH).
Directions work well, allowing the "from" directions to be taken from "center of map" which is useful. As reported by others, there is no audible direction of any kind, no voice or beeps etc.
I didn't notice any lag in map drawing, that is, no blank space was ever shown, the map just scrolled in the direction of travel and seemed pre-fetched.
Thats about all there is to the BBmaps application, and dissapointing as it's features are, it is functional and works as well as expected. It's worth noting that there is no way to check the other data from the GPS, such as battery life, signal and satelite info etc...
Overall, pairing was super simple and it was a solid, reliable experience. The Holux is super small, (the 240 must be really small!) and very sensitive. After initally testing it out on the dash, it worked equally well in the compartment UNDER my stereo and even from my shirt pocket!
