No GPS Signal
TomTom GPS Navigation Device
Severity: ModerateWhat it means
TomTom 'No GPS signal' (or 'Waiting for a valid GPS signal') means the device can't see enough satellites to work out where you are — the map sits still or shows you in the wrong place.
Most often it's a cold start: the device has been off a while and needs a few minutes to find satellites.
The other usual suspects are a blocked view of the sky and a windscreen that interferes with the signal.
Affected Models
- TomTom GO, GO Discover, GO Supreme, GO Classic, GO Essential
- TomTom Start and Via series
- TomTom Rider (motorcycle navigators)
- Older TomTom ONE, XL and XXL units
Common Causes
- Cold start after weeks switched off — the first fix can take five minutes or more
- Parked indoors, in a multi-storey, or under a carport with no sky view
- Mounted low or behind a metallic / heated windscreen strip that blocks GPS
- Tall buildings or dense tree cover overhead
- QuickGPSFix data out of date — the device's prediction of where satellites will be expires after a few days
- Failed internal GPS antenna (rare)
How to Fix It
-
Get outside with a clear view of the sky and wait.
A true cold start genuinely takes a few minutes — give it five to ten before you assume a fault.
Don't sit under a carport, a bridge, or beside a tall building while you wait. -
Reposition the mount.
High on the windscreen, near the rear-view mirror, with as much open sky above it as possible.
Keep it clear of the metallic sun-strip some windscreens have along the top edge — that band blocks GPS. -
Update QuickGPSFix.
Connect the device to MyDrive Connect on a computer (or use Wi-Fi on newer GO models).
QuickGPSFix tells the device where the satellites will be, which turns a five-minute cold start into a few-second one.
It expires after a handful of days, so a stale QuickGPSFix is a common cause of slow fixes. -
Charge the device fully.
On some models a low battery makes GPS reception unreliable.
Give it a proper charge from a mains USB charger before testing again. -
Force a restart.
Hold the power button for about 20 seconds until the device restarts.
That clears a stuck GPS state — it's the standard TomTom soft reset and it's safe to do anytime. -
If it never gets a fix outdoors, contact TomTom.
If the device sits outside with a current QuickGPSFix and still can't lock on, the GPS receiver has likely failed.
Contact TomTom support — depending on the model and age, that's a repair or a replacement.
Frequently Asked Questions
How long should the first GPS fix take?
From a real cold start — the device off for weeks, or moved a long way since last used — five to ten minutes outdoors is normal.
With QuickGPSFix up to date it drops to under a minute.
If you're regularly waiting more than ten minutes outdoors, something's wrong: usually the mounting spot or an expired QuickGPSFix, occasionally the antenna.
