Maybe you can update them through Garmin Express or the Garmin phone app if that'll connect to it through the wifi. You might be able to get some open source maps. But I'm also not sure if that model Edge accepts them. Another member will probably will remember.
I was going to mention the map issue but decided one step at a time. (Who knows if he’s even reading this. Maybe, he’s already using newer maps.)
If he’s using an old map, he should try new ones and one that is free. (Don’t pay for maps.)
New maps should work on the 705.

Be sure to pick a Latin version of one of the Garmin options.
Oh, the maps that came with that device are not updatable. For maps from Garmin, you’d have to buy new versions. These maps you purchase from Garmin don’t include updates.
Again, do not buy maps.
(The newer Garmins provide free updates for maps that come with the unit.)
