I would assume that the wash select has a version E motherboard in it. You can pull the motherboard, and Unitec can update the board to turn it into a G-1 revision. Then, you can buy the internet update card processing, that will come with a new double sided reader, and a high speed " modem" that would be programmed with your information.
Some operators don't want to pay the fee for internet, and believe it or not, in some areas, internet is still not available.
