GPS Antenna Error
TomTom GPS Navigation Device
Severity: ModerateWhat Does This Error Mean?
Your TomTom cannot receive satellite signals because the GPS antenna has an error. This can mean the antenna is being blocked by your car's metal, a metallic windscreen coating, or — in serious cases — a hardware fault with the antenna itself. Start by moving the device and checking its position before assuming a hardware problem.
Affected Models
- TomTom GO 520
- TomTom GO 620
- TomTom GO 5200
- TomTom GO 6200
- TomTom Rider series
Common Causes
- Device mounted in a position blocking antenna reception
- Metallic windscreen coating or tint
- Internal antenna hardware fault
- Software glitch reporting antenna error incorrectly
- Device damaged from overheating or a drop
How to Fix It
-
Mount the device on the windshield in a central position with a clear view of the sky.
The antenna needs an unobstructed view above. Dashboard mounts can block signal. Centre-windshield is best.
-
Check if your windscreen has a metallic coating — these block GPS signals.
Some windscreens have metallic infrared or UV coatings that act like a Faraday cage. This requires an external antenna solution.
-
Take the device outside away from the car and test in an open area.
If GPS works outside the car but not inside, the car (not the device) is blocking the signal.
-
Perform a factory reset (Settings > System > Factory Reset).
A software bug can incorrectly report an antenna error. A factory reset clears this.
-
If the error persists outdoors, contact TomTom support.
An antenna error that appears consistently outdoors in open areas indicates a hardware fault requiring repair or replacement.
When to Call a Professional
If the GPS antenna error persists outdoors with a clear sky view and after a factory reset, the antenna hardware is likely damaged. Contact TomTom support — this is usually covered under warranty.
Frequently Asked Questions
Can I use an external GPS antenna with my TomTom?
Some older TomTom models had an external antenna port. Most modern TomTom devices have an integrated internal antenna with no external port. If your car has a GPS-blocking windscreen, an aftermarket mount with antenna routing may be needed.
How long should TomTom take to find GPS signal?
Usually 30–60 seconds outdoors with a clear sky. After a long period of storage, it may take 2–5 minutes for a cold start. If it takes more than 10 minutes in a clear outdoor area, there may be an antenna problem.
