Downloading maps

Gents,

First off i am a layman as far as computer terms are concerned. I have downloaded the trial version of backcountry and i love it. I have both the TDS systems Nomad system as well as a recon with the Holux card.

Here is my question, Noone has answered my calls or emails so maybe you gents can help, My recon does not have WIFI, how do i download maps to it? Maybe a stupid question but i cannot figure this out. It was incredibly easy on the Nomad you simply click on the download tab.

Any help would greatly be appriciated.

Thanks,
Ken
