No gps signal

Hi guys, I need your help again...
Long story short- I've completed the non idrive to cic retrofit few weeks ago and it's all coded updated and works as it should except now I'm having a nightmare with the gps antenna. Was working fine till 2 days ago where I went on a long trip where half way through it lost gps signal and the car though I'm still at my home address in UK even though i was in France. What's even worse is that while I'm in the car my samsung phone doesn't get any gps signal at all and also 3 other passengers with 2 iphones and another samsung had no gps. Looks like for some reason the cic/gps antenna is blocking any gps signal completely.
The cic did eventually recognise that I'm abroad and did show that I'm in France but still it's pretty unusable therfore I'm going to disconnect the antena for now so I can use the phone as otherwise we have no nav working at all.
The antena is off ebay but read that people have good luck with it.

Any input is highly appreciated as I'm confused and not sure where to start from with this one.

Thanks beforehand!

Unlikely that the antenna itself is causing an issue.

At worst it would fail to pick up the satellite signals but it would not block other devices nor generate an interfering signal.

It sounds like that there is something in the car emitting interference.

Grab a gps satellite tracker app and while using it walk away from the car at various points in a circle.

You could use it to build a map of sorts to help you pinpoint where the interference is originating from... or a signal scanner could be used...
