Some of these units include StreetPilot c3xx, StreetPilot i2 / i3, StreetPilot 72xx, StreetPilot 75xx and some Kenwood models.
There are also units that need updated firmware to be able to work with SDHC cards (cards > 2 GB), like zūmo 4xx and zūmo 5xx.

Then there are also units that do not recognise map files larger than 2 GB.
Some of these units include nüvi 3xx, nüvi 6xx, nüvi 5000 and StreetPilot c5xx.
