I'm looking to install a new GPS tracking system for my trucks. I used ATTI in the past and was very disappointed. I was attracted to the idea of no monthly fees-just the units and the software, but the software seemed antiquated and when there was a problem, they were unable/unwilling to fix it. I'm not going to throw good money after bad ($5,000+ wasted) I don't need real time tracking but want to use it for oversight and efficiency purposes. Any suggestions?
