Firstly I appologise if this is already here somewhere,and any help will be greatly appreciated.I have bought a mio spirit 578 from pixmania with full european maps.When I bought this I assumed it would have full postcode search but it doesnt.As Im a courier with lots of rural its not much good to me.If anyone knows an unlock so I can use igo or even if there is a full postcode download for this device.
I can help with unlocking too. My favourite procedure involves all scripts from SD card, so the internal flash always remains intact. I think this is the safest way and the most user friendly for unlocking mio devices with SD slots. If you are willing to try my unlock, just send me device.xml file which you can find on the internal flash. It will help me identify all the necessary parameters for the unlock menu for this particular model.
