I have the 2200T and I'd like to know what builds will work with this unit, so that I can get all the features working? I've tried the 743-793 build and it comes with TMC, landmark view 3D, I have Zagat POI installed, curve warner, speed camera detection, etc. The only thing I can get working out of all of these is the TMC. Are there any other builds I can try that will get everything working? I have all of the codes in the device.xml file so I don't think that is the problem. BTW, when I use the 743-793 build it turns my 2200T into a 2310. Anyway, thanks for any help on this.
