I don't know if it works with any other device but it works for sure with the omnia.
I won't post links here because I don't think it's allowed here but I could provide the information on another way that's possible on this board.
We all know that the TomTom 7.450 only works one time after a softreset. So I thought that it should work with the new version 7.915.9196. And so it is. But if you want to install the 7.915 it says that the device isn't compatible with this software and it doesn't install. So what to do? I installed the 7.450 on the omnia and the 7.915 on my HTC. The next thing to do is to copy the files (only the files and not the other directories) from /Program files/navigator/ on the HTC to the same folder on the Omnia. So we have the new version now running on the Omnia but unfortunately this version doesn't accept the maps anymore. But I found an easyusetool_frontend somewhere in the net which is designed for the TT8 but does good work here (you just have to rename one file). Alternately you can buy buy the map for the TTGo8 and it works for this version of TomTom. I used TT7 now several times on the Omnia and it works like a charm. Don't forget to let TT use the correct GPS-port without GPSGate (or PortSplitter).
just do it! - otherwise shoot me a pm....
