Well... I recently moved to Finland from Canada and shipped my car over (which had the Z110BT installed). So, I took a chance and tried the upgrade to the EU maps. After reading the entire thread, it doesn't seem like anyone has done z110BT -> F20BT. All that was attempted was F10BT -> the z110BT hack -> F20BT. So, here's what I had to do:
1.) Installed the ShortFuse Hack (This went smoothly - Thanks Shortfuse!)
2.) Then I inserted the EU Version of CNSD-110FM SD1
- So this didn't work. Inserting the SD Card did nothing
3.) Downloaded the US version of CNSD-110FM SD1 and inserted it into the unit
- This worked. It prompted me the message. So, I chose not to continue
4.) I copied the US version of CARDINFO.cif onto the SD Card of the EU Version of CNSD-110FM SD1 and replaced the EU version.
5.) I inserted this SD card into the unit and it worked!
I can confirm that my z110BT now has the F20BT Software and Maps. I get the new UI and I have the EU maps.
But... there are a few drawbacks.
- Navigation does NOT work (You can't search for the address, can't search for POI's, it just gets stuck at the loading screen, etc)
- If you try to arbitrarily pick a spot on the map and select to Navigate there, it kind of works, but you don't get Voice Guidance.
- The regional settings are still for US and Canada, so I can't set my clock to the correct time. The most I can do is +9 hours which is 1 hour off from Finland time zone.
Other than that, everything seems to be working.
