The Proton Exora came together with a free GPS.
After using it once, I didn't think it was that great. The maps were not all that detailed and the driving directions were not that accurate. An example was when the GPS wanted me to drive another 2 km to make a U-turn when there was a roundabout just 100m in front of me.
So..... went on an exhaustive search on the net to find a solution.
Found out that the Proton GPS aka Lokatoo was formerly sold under the MyNavi brand. Not sure what GPS software it runs but the maps are provided by TM. All this sounds good so far but then you are dependent on TM to update the maps and Points of Interest (POI) which doesn't sound so good anymore.
The unit runs on Windows CE 5.0 so after some searching I found out that Garmin Mobile XT (GMXT) could also run on Windows CE. So went to LowYat and got the software installed. After looking at both Malsingmaps.com and Malfreemaps.com I decided to go with Malfreemaps.com as the maps are free and constantly being updated.
So, after much searching and some initial issues with the installation.....
So, to all the Proton GPS owners out there, it is possible to run GMXT which is so much better and has so many, many, many more POI's.
