Hello folks this is a bit random ! I've been struggling with my sat nav .Gps for the past couple of weeks with poor reception I've found the cause and its my phone holder in the van (it's on of the ones where you place your phone on a pad and it grips onto your phone without any clamps (bought from asda) it takes a good pull to take it off , my GPS signals were all less than 30 ! I've taken the back off my phone and opened the contacts to the GPS antenna and I can now get a strong signal sat in the conservatory .
Hope this is helpful ! If this isn't applicable here could the admin please move to a relevant place tia
