VW Taos GPS Signal Loss, Common Antenna Fix Needed

I experienced similar car GPS issues on my 2020 VW Tiguan. The vehicle GPS system completely lost satellite connection and displayed error codes, matching your symptoms. The root cause was a defective GPS antenna, which required professional diagnosis at an authorized service center. The antenna repair involved replacing the complete roof-mounted GPS module since these units are not serviceable individually. While not a critical safety concern, a faulty car navigation system can be problematic for daily use. The repair process was straightforward but required specialized diagnostic equipment to properly calibrate the new antenna to the car navigation system. Key indicators it was the antenna: No GPS signal regardless of location, System error messages, Navigation screen showing no satellite connection, Other wireless functions working normally This is typically not a DIY fix as it requires proper diagnostic tools and calibration. Based on the symptoms you describe, your Taos likely has the same antenna module issue that my Tiguan had. Recommend having it checked at a certified service center to confirm the diagnosis.

Thanks for sharing your experience with the GPS module issue. The symptoms you described match exactly what I am seeing with my Taos. The constant signal interference and lack of satellite connection is really frustrating. I will schedule a dealer visit based on your feedback about the roof antenna replacement. Mind sharing what the repair cost was in your case? Also curious if youve had any further issues with the car navigation system since the fix?

Thanks for asking about the follow-up costs. I had the GPS antenna repair done last month and the total came to 200€ for the complete fix, including parts and labor. The car electronics specialist confirmed it was indeed a faulty GPS antenna unit, exactly as suspected. The vehicle GPS system has been working flawlessly since the repair. The satellite connection is now stable and reliable, with no more signal dropouts or error messages. The navigation accuracy is actually better than before the issues started. One thing worth mentioning is that the repair shop needed to perform a full system calibration after installing the new GPS antenna module. This extra step ensured proper integration with the existing car navigation components. For anyone else experiencing similar symptoms, the investment was definitely worth it. Having a fully functional navigation system really makes a difference for daily driving, and the fix has proven to be permanent so far.

I ended up taking my Taos to the VW dealer this morning after seeing your comments. They confirmed it was definitely the same GPS antenna issue you mentioned. The service tech showed me where the GPS module was damaged, causing all the signal interference problems. The repair cost was similar, around 190€ for parts and labor. They had the replacement antenna in stock and completed everything in about 2 hours. The satellite connection is now perfect and the navigation system is working like new. Really appreciate the guidance, saved me time troubleshooting and gave me confidence to get it fixed at the dealer rather than trying other solutions first. The car GPS is back to normal and no more error messages about lost signals.
