Not so easy..The thing is you need to completely swap your current original iGO primo version on your SD card with the "fixed" (crac*ed) iGO primo version, otherwise new maps won't work (licence issues). So you need to make a full backup of your original SD card first, than you can format it. Next step is to download iGO primo which will be your new navigation on your SD card and it will accept new maps. To make things easier I have prepared everything for you. It's fully configured for your Blaupunkt New York. You have download link on private. I could share it here in public but it's a private dropbox link so I don't want to risk my dropbox account as I was already warned once..I hope moderators will understand

When you'll have new iGO primo version on your SD card, than just add your preferred maps. You can find it in map section.
