Which navigator with GSM / GPRS to choose for the taximeter program of your own design?

Question

satellite navigation

1) the navigator receives GPS coordinates and sends them to the server via a timer via GRPS, and at the same time shows data based on the coordinates on the program display.
What device is suitable for this - with a minimum set of functions and budget?
Something like www.texet.ru/gps/tn606.htm
2) on what and how are the start menus written for such devices, what can you read about it?
Thank you!

Answer 1

Device - any navigator with GPRS and the ability to install software (theoretically).
Some information about car navigators:
1) The vast majority of devices are running Windows CE 5.0 / 6.0 (namely 6.0 - not R2, not R3). And it's NOT Windows Mobile.
2) The main difference between Windows CE is embedded systems, there is no one distribution kit for everyone, the system image is developed for each specific device; the manufacturer at his own discretion configures the system, includes or does not include certain modules. An image of a specific system for developing software for it and testing) can be obtained from the manufacturer (or not - depends on the manufacturer).
3) The main difference between Windows CE 6.0 in relation to your question is the presence of a GPS Intermediate Driver, which allows you to abstract from specific hardware and a real COM port, and also simplifies the task of working together with GPS (your program and navigation, for example).

4) Development under Windows CE 5/6 is possible in Visual Studio 2005/2008 (CE is no longer supported in 2010). For Windows CE there is a .Net Compact Framework (almost .Net Framework, with some changes and cuts). VS already contains an emulator for Windows CE. To develop for a specific device, you need either the device itself (connected), or a system image and an emulator).

Based on this, the question needs to be clarified:
1) You are going to develop a program for a specific device or program that can potentially be installed on a number of devices?
2) Is your program and navigation program required to work simultaneously?
3) I did not quite understand about the start menu.

Answer 2

Look towards application development for Windows CE 5/6. The emulator is built into VS2008+
C GPS will have to work through the COM port.
Almost any navigator with GPRS and the ability to access the desktop will do.

Answer 3

It seems to me that it is worth trying to contact the Chinese and order a batch of cheap hardware on WinCE or Android
