Best GPS software for carputer?
What is the best PC software to install go use with a GPS receiver on a carputer? I know they all have upsides and downsides, but what do you think? I'd like to have voice directions for me and voice commands for it. Also, be able to put in my own POI's easily and I know Sirius and XM are working on adding realtime traffic updates to nav systems, so compatablity for that would be good. Also, overall accuracy and helpfullness.
I know the Pioneer Avic N1 is known as a great system mostly becasue of it's good GPS (like 12 million POI's, mult. views, etc.). Is it possible to hack their software and use it with your own receiver? Or use their GPS receiver and software but not buy their unit? Thanks for any help.
