You can image a hdd with the maps you want but the issue that most people run into is that the AM/FM part of the radio works differently depending on what part of the world you live in. This pretty much makes the unit un-useable for anything other than navigation.
Many Thanks for your kind repose
I did use US radio's in EU. The FM reception is not very good but it works Ok for local powerful stations. the main difference (as I recall) is the FM frequency change steps
The other problem is DVD region codes but there is a way around this.. There are lots of software products that allows the change of format or copy the DVD into all regions version. I also read somewhere that you can actually change the region code of the Z2/Z3 by entering into service mode
Now the big question is
Did anyone try to get into the unlocked disk ...find where the US maps are and change replace them with Eu maps ?
there must be a folder that includes all the map images that can be manually replaced. Since I do have the EU map images unlocked already, I want to try to replace the MAPS data..rather than the whole unlit software image. If this would work then you can use this unit anywhere in the world where the TomTom maps are available.
DOES ANYONE KNOWS HOW TO REPLACE THE MAPS ONLY ?
Did anyone try to record on Z2 a non-original (copied) CD (normal CD not MP3) ?
Final Question: where can I download the service manual of the Z2/Z3 ?
Many thanks again for your help everyone
