The kenwood site says that only Kenwood/Garmin maps will work. I just bought the head unit in January of this year and the map is outdated. They want me to pay $110 to download the updated maps and even then it's only 2015.2 instead of the 2016.1 that was just released.

Can anyone help me? Can I use a SD card with unlocked Garmin map? Does anyone have a Kenwood/Garmin updated map?

Thanks in advance
