Can anyone help please

I had Igo primo maps on my new unit, and a mate lent me his updated igo8 map to try, it downloaded and worked, but when I put my own map back it would not load.

So I think the igo8 has updated the software so now i'm stuck.

I need a ce windows 6 igo8 map for the unit to work again, but where from, have checked the web and there are some there but when it comes to downloading anything i am no good at it

Could someone please provide the legal links to where to get them or could someone do it for me and send me the SD card, I will return a new SD card to replace

I am stuck without sat nav until i can put the map in

send me a PM if you can help please
