I bought a stereo with the freeview and gps have gone to fit my stereo today and it says that there is no gps software and the tv/freeview won't work and I'm sure it is searching for channels in Germany and when you change it to English and come out of the menu it goes back to Germany.btw..it is from Xtrons..how to work it out?

 

ic..mine is also xtrons.u can insert the SD card into the GPS slot and go to the GPS mode. You’ll find the GPS setup.After that, please turn to the GPS mode, choose the navigation menu, you will find the map is loading. Then you can use the GPS navigation.
Regarding the freeview, please save the change of English before leaving the menu.
