There is no such restriction with a 500 or the 700).The Road Mate is a well-designed, portable unit, with a large, bright color touch screen and easy-to-use controls.

(There is also a difference in package contents -the 700 does not include the A/C adapter, USB data cable, and CF card found in the 500 package).The unit has a jack for an external amplifies antenna.(If Windows does not detect the Road Mate, see the Windows 98 driver document on the support page). Follow the "Read Me First" poster included in the box.Don't even bother with other doc, some of which is confusing (the pamphlet with basic instructions for uploading map data to the Road Mate has a reference to a non-existent Road Mate 300, indicating that the ability to change data on the CF card would be locked out after 45 days.The map software is already stored on the micro hard drive ready to go!The Magellan Road Mate 500 (about 0), get latest prices (HERE), comes with a startup kit: Road Mate 500 unit, universal mount, dashboard/air vent mounting bracket, cigarette lighter power for car use, A/C adapter for home use, standard mini USB to USB cable, 128 MB pre-authorized CF card, printed doc ("Read Me First" fold out, PC application Quick Start Guide, Basic Operation Instructions Manual, extended warranty info, registration info, promotional material), documentation CD (65-page reference guide and 9 page Welcome doc which provides a good overview of the unit, but is more marketing document than anything) and 4 CD software and mapping data package.The supplied mapping data from Nav Tech seems fairly complete.The Nav Tech data appears to be from late 2002 or early 2003 which is about as recent as any comparable unit.
