Consumer report has released a look at GPS systems... Eighteen GPS navigation systems from 11 manufacturers were tested for ease of use, guidance information, route options, and portability. Fourteen received a 'Very Good' rating, while the Garmin Nuvi 660 ($700) led the way with an 'Excellent' rating, edging out its older Nuvi 350 sibling that topped the last round of tests (Portable GPS navigation systems, Aug. 2006). The remaining three models, which included the lowest-ranked Rand McNally GPS Navigator ($350), received a 'Good' overall score. Prices ranged between $250 and $700. A full list of portable GPS navigation system ratings and reviews can be found in the magazine's October issue, on sale now, and online at http://www.consumerreports.org/.
