If I understand the question correct, you are asking about the traffic updates that are available? That is a sdubscription service and requires that you have one of the satellite radios. XM or Sirius I think. My nav system doesn’t have that option.
Pearl Izumi is releasing 700 of these for sale. We have about 80 of these left. Go to http://www.bicyclinghub.com/gachcyjebype.html
Up until recently you would have to purchase a laptop based navigation system for truck routing which wasn’t very good. Right now there is a new company that makes specific portable GPS for truck drivers where you can input your height, length and weight and it will guide you around all low bridges and restricted routes. To to this web site for info on where to purchase one: http://www.gps-planet.com/wotrgpsun.html
You can even add a back-up camera that would work right on the same screen. I never personally owned it but I heard good reviews so far.
Good Luck.
I heard that they were. I haven’t heard from customer service yet.
which is a better GPS out of Garmin nuvi and TomTom One if they have exactly same features & exactly same price.
I have confused between garmin 260 and tomtom one 130S
i am concerned about which is more comfortable to use in terms of quick reading of directions and who is more helpful in traffic and stuff
as a whole which is better for same price?
