There is no exact tutorial showing all the interface or system. You will need to learn and understand part by part and integrate it. That is learning.
It depends on your requirement, 628 can receive GPS using UART's RX pin and after process send it out through UART' TX pin to 887 UART's RX pin.
1st try to interface the GPS with computer and understand what is the data, then interface with 628 and develop program for it. ..... step by step.
