I have my TX installed SA2007. No problem in installation. After checking Application then select All, I can see the software and activate it easily. However, cutting maps from the desk top SA2007 and then syn into my 2G card in the TX is a painful and time consuming process. To have the maps within 800 KM from Toronto Canada ready, I spent probably more than 24 hours. And then I come to the saddest part of actually running it. For instance, It took a whole night to route me from Toronto to Chicago. And if you zoom out more than level 6, redrawing map takes forever.
In my opinion, SA2007 is not for handheld although it has been promoted like it does. Because I refuse to further invest on a blue tooth GPS, I can't comment on how it actually works on the road. However, I did have it installed with my laptop and my Garmin 76 GPS handheld. They works together wonderfully. Routing is done in a blink. On the road, voice instructions are loud and clear . Off-road rerouting works well too.
I am looking into TomTom instead now.
