There is a GPS problem with tunnels and so

To mention it again. Between Fenix 6 and Epix 2 on one and the same lap are >500m offset at 20km.
Take a look at the pictures. I have 2 tunnels on the way (Frankfurt airport). Both are 200 and min 300m long.

With the Fenix 6 I drive, as with the Epix 2, with 4.63km pure. I come but, correctly, out of the tunnel with ~5.1km.

With the Epix I go in with 4.64 and come out again with 4.67km. That's nonsense. But explains why the devices have such a difference. The Epix can not calculate tunnels out.

All the errors in the GPS, but also in the altitude table etc. are unfortunately absolutely frightening.

Knowing Garmin, they will not fix it.

0 TobiasLj over 3 years ago

Once you are out of the tunnel it should add the distance from where you lost GPS reception to where you get reception again unless that is an unrealistic change.

I would open a support ticket and I would also try other activity types (still biking) to see if this is specific to the bike activity or not.

0 Hexxer over 3 years ago in reply to TobiasLj

I must admit that I hoped that I am not the only one who has a tunnel on his route.Ticket oder Mail ist written

0 Hexxer over 2 years ago

Same....all the time. I wont stop till Garmin said it is a GPS Chipset bug:

- they cant fix

- they will fix

https://forums.garmin.com/beta-program/fenix-7-series/public-beta-reports/i/public-beta-8-35/trackingproblem-in-tunnels-with-bike-still-exist

As i opend a case at the german support they say that the watch must first get used to me. Realy, i got the original mail. Driven some hundreds of kilometer and nothing happens. Looks like the watch dosent like me.

Tunnel is 400m long. I have 3 tunnels on my round.

0 ShannonA over 2 years ago in reply to Hexxer

The gps signal can’t find you in a tunnel. It’s common knowledge. What are you whinging about here.

0 trux over 2 years ago in reply to Hexxer

Buy a speed sensor if you want to measure the distance without GPS signal.

0 Mladen T over 2 years ago in reply to ShannonA

He's not talking about GPS signal but on how the points get connected before/after the tunnel.

With F6 it was ok, with Epix 2 not ok and, from what i understood, it's happening only with bike activity.

0 Hexxer over 2 years ago in reply to ShannonA

Nice. So the Fenix 6 have som magical Sensor inside? Because with the Fenix 6 the track was correct.
The GPS Chipset inside the Fenix 6 was able to connect and measure the distance of the two points.

I drive thru this tunnel dozen times with the fenix 6 (i got 3 tunnels on that round) and lost near 700m....no critical problem, but the Fenix 6 can handle this.

0 Hexxer over 2 years ago in reply to Hexxer

As you can see here (i cant Upload direct in the answer) with the Fenix6 it was perfect
