Can one of you 'Experts' explain to a mere computer user what exactly I would need if I were to get Street Talk. I know I need Pakmate (but why can't I use an off the shelf PDA instead of having to spend mega bucks just because its for VI use, something called Destinator (having looked at TotalGPS.Com I am 'blinded' by science as there appear to be two or three Destinators (why, what are the differences and which one would I need), a GPS Blue Tooth Receiver (which one, where do I start) and a Blue Tooth Card (again which one and where do I start)? I have stupidly wrongly installed Wayfinder on my memory card on my phone and now can't seem to delete it or overwrite it. Any suggestions? Sorry if these queries are supposed to be 'off list' but I am so confused about the whole navigation business. Lastly, does Street Talk have a motorised function like Trekker?
