Hi, I just got the SRi-V but hold NO hope of any hacked maps or POI camera info.
However I have a garmin 2595 that accepts all the good stuff. I sugest u do the same. However the default satnav seems to do a good job apart from the pirate mentality of holden and GM (usa) who can only think they can extort updates at $300 or more per update and have no extras at all. RRRRRip offf.
Personally i can say & from what others have said the that the Garmin 3490 Tracker is a far superior system on the market as I post this comment, just look at the evaluation <a href=http://www.squidoo.com/travelling-with-the-best-gps-system-the-garmin-3490-tracker>The Garmin 3490 Tracker</a>.
