The Version 7 I mention of course is not the software version, it is the data version of the map data.
Mapsource technically the name of their software product offering.
The data is sold separately (with the software) as different packages.
(TOPO, MetroGuide, CitySelect, CityNavigator etc.)
The map and POI data are updated on a more or less annual basis.
And they charge for it.
Updates to licensed users of the previous CitySelect releases are half the price of a new unlock code.
Many people don't update every year.
The software is regularly updated and it has improved recently (for my uses anyway).
Interface still reminiscent of early windows products.
It is NOT MEANT TO BE A MAPPING PRODUCT. You are of course free to buy something else.
There are other vendors out there and all products have there limitations.
Magellan's dual purpose units require you to press a button to recalculate if you miss a turn.
They have more contour lines but less trails than Garmin in the TOPO version.
Lowrance has 50' contour lines & good forest road & trail coveraage, but they have their issues too.
Everything has it's trade-offs. Such is Life!
There are new products coming out all the time and each have their strengths and weaknesess.
Some units have better screens, better User Interface, better street or TOPO etc.
I know of one in the works that will impress.
