Hi everyone, 
This is my old long project and finally, it is Done!
Looks good and working well:)

Thank you for watching

Important remark: 

#1
Later, was add a simple filter in the power line of the GPS module. 
Resistor 3 Ohm in series. 
Capacitors in parallel, tantalum 10 mkF and ceramic 0.1mkF.
To reduce digital noise from the GPS module.
