I cycled out of London a year or so ago. before it becomes the A1, it is actually named as the Great North Road on a few street signs in north London.

I think your definition of GPS and SatNav are wrong and I follow wikipedia on this one: Global navigation satellite system - Wikipedia, the free encyclopedia


A GPS is a GPS even if it has maps or not, like a cellphone is a cellphone even if it has web-access or not.

I only refer to the use as perceived by many... Trying to make an analogydoh
Both terms apply to the one device which perform the same function, namely to triangulate your position in lat/long/height. Nothing else.

The rest is just software, supplied by the maker, in the device to relate your position to another position on a known grid. The (street) maps and direction commands are just a fancy way to display that to the user.

IM glad you called him out:) SatNav being the marketing name someone made up as GPS has been GPS since its creation.

I did use maps for central america, but for south, I literally could not be bothered tracking down a decent maps, and just started writing down town names on a notepad with a couple lines. Didn´t ever get lost, I actually talked more to locals and probably prevented myself from being over confident reading maps on the road and taking wrong turns.
