I do have the US CNSD-210FM installed already, is that a problem? How can I force it to re-load with the EU info?
Then the App Version must be 3.00x. I believe both US and EU upgrades use the same version number. The installation software will only upgrade a lower version.
I think you might be able to force load it by hacking the version number using TestMode. However, that is beyond my skill level. It might also be possible to replace the US maps with the EU ones. I believe something like that was done for AU maps, with mixed results (POI didn't work).
If it were me, I'd sell my HU (an upgraded Z120 has extra value), and buy an un-upgraded Z110 or Z120 off ebay. Much easier and less risky. Then you should be able to install the EU CNSD-210FM.
If you want to try hacking your existing unit, take a look at the Condi Hack thread. http://avic411.com/i...dated-13062011/
But you better know what you are doing or you could brtick your HU.
