Portable GPS navigation systems are so useful since you can use them in your car and carry them with you when you stop and get out in the real world. The only problem I have with most of the systems from TomTom and Garmin is how bloody expensive they can be, costing as much as $900 or more. Lowrance flies in the face of that problem with the release of the iWay 250c for only $350. The 250c has a 3.5 inch touch screen and uses the most excellent WAVTEQ maps for providing the standard navigation features like turn-by-turn guidance. It uses an SD slot for storage so battery life must be pretty darn good.
