T-Roc GPS Signal Loss: Antenna Fix Guide

I experienced this exact GPS signal problem on my 2019 VW Tiguan last winter. The navigation system showed similar error codes, and the GPS antenna turned out to be the root cause. The antenna repair involved accessing the roof-mounted GPS antenna module, which had water damage from a small crack in the housing. The main symptoms matched yours, complete loss of satellite connection and persistent error messages on the infotainment display. This was a serious issue requiring specialized diagnostic equipment to verify the antenna failure. The repair involved replacing the entire GPS antenna assembly since individual components cannot be serviced separately. Key points from my repair experience: Complete diagnostic scan was necessary to rule out other electrical issues, The GPS antenna replacement required removal of some headliner components, Testing after repair included verifying satellite connection strength, Total repair time was about 3 hours at the workshop Make sure to choose a shop with VW-specific diagnostic tools, as generic scanners might not properly identify vehicle GPS system faults. The antenna repair restored full navigation functionality without any recurring issues since then.

Thanks for sharing your experience. Almost the same happened to my T-Roc last month, complete GPS signal loss and navigation system errors. The mechanics discovered a faulty GPS module that needed replacement due to corrosion. Just curious, how much did you end up paying for the satellite connection fix? And has the GPS antenna been working properly since the repair? My bill seemed steep at 480€ for parts and labor, so I would like to compare notes. Good advice about finding a shop with proper diagnostic tools. The signal interference issues can be tricky to diagnose without the right equipment.

Had my Tiguan repaired about 2 weeks ago and the car navigation is working perfectly now. The GPS antenna replacement cost me 200€ total including labor, which seems significantly less than what you paid. The satellite connection has been rock solid since the fix, no more signal drops or error messages on the display. The lower cost in my case was likely because the car electronics diagnostic showed a straightforward antenna fault that didnt require extensive troubleshooting. The GPS module itself was fine, just the antenna needed replacement. The repair shop used VW-specific equipment to verify the antenna repair resolved all satellite connection issues before returning the vehicle. Makes me wonder if your higher bill included additional diagnostic work or if they replaced more components than strictly necessary. While GPS antenna problems are common, the repair costs can vary quite a bit depending on what exactly needs fixing in the car navigation system.

Just got back from the mechanic today for my car GPS issues. They replaced the navigation antenna and did a complete system reset. The repair took about 4 hours total since they had to remove several interior panels to access the wiring. The final cost was definitely on the higher side at 480€, but at least the car navigation is working perfectly now. No more signal interference or error messages on the display. The GPS signal is actually stronger than before the problems started. The mechanic explained they had to use specialized diagnostic equipment to properly test the satellite connection after the repair. While expensive, having a properly working navigation system is worth it, especially since I rely on it daily. Seems like GPS antenna issues are pretty common in these models. Good to know others have dealt with similar problems. Really appreciate all the feedback about finding a shop with the right diagnostic tools, it definitely made a difference in getting it fixed right the first time.
