Re: need project help

Congrats for selecting the project.

Let me clear few points to you.
1. You can take fastrax GPS module low cost, or SIMCOM, or wavecom.
2. google map are all paid features, so you cannot download GPS map free of cost.
3. These receivers want only TX and RX pins as our serial communication. So you can interface GPS to serial port.
4. LCD is common, you can interface as you normally do.

done this project 3 years back. come back for any help.
