as those were origionally built for the chinease market , but then sold in the UK
there is a major problem
the chinease havee there own gps system BeiDou Navigation Satellite System (BDS)

on a rainey day with the gods in your favour , and standing on high ground , you :may: get a signal

I had one on a bobber i built , bought from a :reputable" uk suplier for sabout £150 I could set off from my house and drive thru 5 speed csmeras with nothing ion the display

DO NOT buy shite from ebay (from china) , buy from uk suplier of terms that you can return, if it will not pick up european sat sys
