I was considering getting an external Bluetooth GPS receiver to work with my Nokia N75 and I wanted to know if anyone on the list has experience with the various GPS software for cellular phones. I'm particularly interested in the Wayfinder Access software from Sendero group because my Nokia N75 is using the Talks premium screen reading software which is also sold by Sendero Group and I know that both software packages work together. If anyone has experience with the wayfinder Access software could you please speak up so that I could talk with you off-list to see if this software is really something I want to pursue. If people have experience with other GPS software on cellular phones please relate your opinion of how that software works in case I decide to go a different route. Thanks! Scott
