timp4411 & tom1807,

What would you wish to be patched in HomePort?

GMA files are not used with g2/g2 Vision maps.
Therefore, how could any firmware update effect the unlocking of g2/g2 Vision maps.
AND
HomePort will already display locked g2/g2 Vision maps without the need for a UNL file at all.

Although a GPS device will not display a locked g2/g2 Vision map that is on a SD card without a UNL file, as it will show "can not unlock maps."....

... if that same GPS device is connected to a PC via a USB cable, HomePort will happily display that same locked map, without a UNL file, from the same SD card. Also, HomePort will still happily display that same SD card with the same locked map, without a UNL file, if the SD card is connected to a PC via a SD card-to-USB-adapter.
