I didn’t blog on Nextel’s initial release of Telenav Inc’s Java based GPS Navigation software for the BlackBerry 7520, but, you know what they say…”Better late than never.”  I just came back from a road trip with a co-worker who actually has TeleNav installed on his 7520 and I must say it that is is a pretty cool application.

TeleNav on the BlackBerry is very similar to the GPS cell phones that you can get from most car rental places.  It displays maps, speed and direction, and best of all, gives you audible driving instructions that tell you when to turn and change lanes.  You don’t have to worry if you miss a turn either.  Telenav will automatically reroute you to get you back on your way.

The one thing that I would recommend for the serious road warrior is a car kit with a dashboard mount and battery charger.  The GPS radio seems to get better reception when it is near the front window and can be a drain on the batteries as well.
