No gps signal

HennessyLV · 08-10-2020, 06:17 AM

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...

I had a similar problem that was solved by buying a new GPS navigator. Garmin DriveSmart 51 NA LMT-S works perfectly and I do not have any problem with signal lose.

Right, OK so where have you mounted the GPS antenna firstly? Stuck to the windscreen? On top of the dash? Underneath something? There is a good reason for asking, depending on your answer

Recently I've retrofitted cic with an ebay gps antenna. So, l've noticed something. Wherever I place the antenna, it shouldn't be below something. It doesn't matter if it's thin or thick. For example, if I place it at the corner of the A-pillar on the dash, it successfully receives the signal in few minutes. However if I fix it below the A-pillar trim, it doesn't work. No matter which antenna I use. So, I also tried it with other brand gps antennas. However in my other brand car, it succesfully works when I hide the antenna below A-pillar trim. I think it's not due to the antenna, but due to the gps receiver inside the cic or the material of the trim. As if Bmw has produced a trim just like a tank armor.

I am also facing a similar problem with my GPS device. I drive a Mazda RX8 and I just recently installed a GPS device so that I could reach my new office the Yellowstone jacket company. But it then started causing problem within it and now I dont know how to fix it.

I'm having some trouble with my car's GPS signal and I'm hoping someone here can help me out as its causing problem for me to reach my james bond leather jackets . I recently purchased a new car and it came with a built-in GPS system. However, I'm having trouble getting a reliable signal. I'm in an area with good cell phone reception, so I'm not sure why the GPS signal is so weak.

GPS reception has nothing to do with cell phones.

GPS needs good line of site to the satellites in orbit.

I am successfully update the maps to 2024 version, but GPS can not find me on the maps... When i enter in secret menu, it tells me that there is not a single satellite and the year is 1980... Does anyone have an idea how to solve this?
PS. When i move the car, the arrow on the map also moves, but in the wrong direction.
Here is some photos:
