CHEAP GY-GPS6MV2 GPS MODULE VS GPS622R ARDUINO LCD CLOCK ODD PROBLEMS

Had a weird issue with cheap gps module, as you see I hot swap them, wait for it to get signal, one works one does not with no real explaination except one cost about 30 quid and the other didn't. Same with adruino uno and nano, the cheap gps does other stuff wrong with other gps libraries, and sort of half works with nearly accurate gps strings with the ends cut off and speed says 1000000 although the clock was right, I give up its makes me mad enough to cry..Its all gps library based so really I haven't a clue, the tiny ardu nano is so chocked full it was a right ball ache trying to get it to work with lcd drivers and gps. Avoid GY-GPS6MV2 maby its just me being thick and lazy.
