I am still having a difficult time. Can you guys help by giving a step by step?
Apologies in advance to those, including the original poster, who might think the following is a little bit harsh. In business, the following is known as a risk assessment. If you look at the original poster's problem, it's a non-trivial business problem that deserves an objective assessment of the risks inherent in the current approach -- depending on amateur volunteers for technical support.
If you are planning to purchase and install 80 of these units and support and maintain them, it sounds like you need to find yourself a consultant with the necessary knowledge.
You still haven't stated whether you have contacted the manufacturer for assistance. Most manufacturers of such devices have excellent tech support and it's part of what you are paying for when you buy the device. If you are planning to purchase 80 of these devices, now is definitely the time you should be assessing their ability to provide you with the level of support you need.
If you don't have the necessary training/education/experience and leave yourself dependent on voluntary sites like this for support, you can find yourself in trouble really quickly. Those with the necessary knowledge to help with any specific problem might not be around when you need them or don't have the time for the detailed assistance you might need.
Even if you can get timely answers to your questions they might not be good answers for your situation. Your application is specific enough that you need the exact answer to fit your problem.
As far as giving a step by step, you haven't supplied sufficient information about your problem. In order to get good answers you have to ask good questions. If you need very specific and detailed answers, you need to ask detailed and specific questions.
If you want a step by step for a detailed procedure you need to be very specific about what procedure you need directions for. Looking back at the previous messages in the discussion it looks like you might be in need of a bunch of different step by step directions for how to get GPRS set up in the device; how to get the GPRS data from the device to a data server somewhere; how to set up a server or get access to one; how to get the data from the server into a map display for visual tracking, and maybe more.
If you can be more specific about a specific procedure that you are having difficulty with -- the exact steps you have taken and the results you are getting, including the specific error messages -- it's possible someone here might be able to help. I'm not sure if anyone has any experience with GPRS but maybe someone does.
Have you seen, or tried to create, a simple diagram of what pieces (hardware and software functions) you need and how they all connect together in order to get the location data from the device in the vehicle to a tracking display on a map on a computer in the desired location?
Do you have any idea how GPRS works? Have you checked with your cellular provider to get the necessary access point information to program the device and also get information about how to connect a computer to their network so you can receive the location data via GPRS? Or how to direct the GPRS data to a service like GPSGate's?
Before you commit to any solution it's time to get on the phone with tech support from the device manufacturer, your cell service provider and the provider of tracking services like Franson's GPSGate service and see how much each of them can help you. If you still have difficulty with that kind of professional tech support, you need to reassess your approach.
If it looks like the problem is with a supplier, select a different one and try again.
If it looks like the problem is that you don't have the necessary experience to pull it off yourself even with the help of good tech support from the suppliers, you need to consider hiring professional assistance.
It's only my opinion, but if you set out to do this it sounds like you already have a lot of risk because of your lack of experience with this specific set of technologies. Do you really want to add to the risk by being dependent on amateur volunteers who might or might not be around with the answers you need when you need them and who certainly will not have the same sense of urgency you do when a problem comes up?
