Hi friends! I have a Wismo Quick Q2406B (without internal GPS device) and a task: it’s necessary to create a part of code consist of subprogram that provides receiving data from external GPS …
Could You all help me?
via UART2, obviously 
I embedded uP as a commercial mass production solution with PIC12F629 interface between GPS and Q2406.
The complete device’s picture shown in gpslocation.net

Why would you need to add a PIC?! 
Why not, as already suggested, just connect the GPS direct to UART2?!
