Tomtom's Pro 4000 and 8000 GPS Units Come with Support PackageSTomtom has just come up with a suite of GPS systems for the "mobile workforce" dubbed the Pro series. The first units are the Pro 4000 and Pro 8000, and while the hardware is essentially unchanged from non-Pro models, there are a few tweaks. Firstly the software has a "menu lock" option, that's supposed to lower distractions and improve driving safety, the maps come with a free update that's to be used within a year, and there's a PIN lock to protect your data. Secondly the support package comes with a two-year extended warranty and a dedicated customer service line. The 8000 also has advanced IQ navigation, which plans routes using actual average drive times, and voice address-input and Bluetooth handsfree calling. The 4000 is out for $330 and the 8000 for $460.
