HP RX5720 - how to run additional maps

[vacantmoments]

I have a HP RX5720 - it has TTN6 and GB maps pre-installed - how do I add maps - i.e. pre-owned USA TT maps on a SD card? Have tried plugging in the SD card but the TTN6 is not seeing the maps?

please check your map version against our map compatibility list.
