My husband drives a Tractor Trailer. He has a Rand McNally TND 510, he bought a accessory for it - a Real Time Traffic Receiver that uses FM Radio Stations that currently uses 98 cities in the USA. He is disappointed in it, it doesn't seem to help him in traffic like he had hoped. What other GPS units would work better, if any, regarding traffic?
Has there been any instances where traffic patterns or roads changed because of GPS use? [more inside]
Do the fancy higher-end features (traffic, eco route, etc.) of auto GPS units actually work? [more inside]
Lazyweb, I need help choosing an automotive GPS navigation unit for a directionally-challenged relative. It must receive traffic updates, have an ability to remember programmed routes, and be reasonably easy to install and use. [more inside]
Does anyone have experience using a GPS with traffic updates (in the Chicago area?) Looking to compare XM Navtraffic to Clearchannel's FM traffic reports. [more inside]
