The integration of GPS mapping and satellite delivered data can bring you real-time re-routing to our car navigation system, ala XM NavTraffic on some Acura and Cadillac vehicles, as long as the traffic data collection is supported in your city. Boaters and aftermarket GPS fans can use the GPSmap 376c from Garmin to display weather overlays on their current map. A 3.8" 480 X 320 256 color screen looks crisp and bright, a battery gives between 4 and 15 hours of use and this, of course, tunes in all 150 channels of XM satellite radio. Radio will cost you $12.95 a month, but weather data, a whopping $29.99 to $49.99 per month. Looks like weather needs a better service model from XM, like NavTraffic which is only an additional $3.99/month for existing radio subscribers. It does however look to be a nice convergence piece of satellite technologies. Plus you could even spill your boat drink on it as it is water restant. Now available at your favorite boat store or online retailer for $800 to $1000.

If you are more of a driver than a boater, the 7" widescreen 16:9 480 x 234 pixel Street Pilot 7200 gives you traffic updates via ClearChannel's or XM NavTraffic service plus weather information albiet more limited than the marine version above. In addition to XM satellite radio, Audible book and MP3 playback adorne this in-vehicle GPS and an SD slot gives you the storage capacity for multimedia and map updates. An integrated FM modulator eliminates the wire between the display and your head unit for stereo audio playback. Look for this unit in December at streeet prices of $1000 to $1200.
