Mazda 5 installation and using a new map.

Hello.

I am writing this post because I am really lost with all those tutorials for mazda 5 tomtom.

I am a total newbie in this topic, I tried all the tutorials in different order, I downloaded all the stuff that was needed to download, activate map and update navcore etc.

The furthest I managed to get, is to a point where I see message that I can't use this map on this device.

I was trying for a week now, and I finally decided to ask someone to walk me through that in clear steps one by one, if there is a chance.

I have new SD card with basic stuff done and I want at least any Europe with Poland map included or (if exist) Poland map.
Thanks in advance,

Paul.
