i know there isnt many Urban Runner owners here but if you are have you looked into the Plus Service from TOMTOM? i have been trying to find a price and a place to purchase it? if you have it, is it worth it?
if you look in the manual that came with the tomtom...you'll find a site address. I don't think it is worth the extra text messaging and such. I use my phone for that....but...it may for some.
