GPS Track Server Reviews

I bought Concox GT06N and using it my car. This GPS tracker server is an alternative to Chinese services which might be not free and often may violate your privacy (I mean somebody is tracking you down...). Of course you need to have an access to a unix/Linux server where you can compile and install server as well as posses some skills to do that. What would be nice to have is a map feature and as author mentioned himself, one can write a simple script wrapper which will translate logged coordinates to a path visualized on the map.
