Greetings,

I was looking for the answer in previous threads but without success. I am using iGO NextGen, 9.18.27.719974 and iGO NextGen 9.18.27.736653, both without any skin. My phone is Samsung A520 F, android version 8.0. Everything works great except one thing. My altitude is completely wrong. I am living in town which is on about 80 m of see altitude. Both of my navigations show about 120m. Is there any chanses to do some correction?

I checked with few free applications from Google Store, like "GPS Altitude" and I am getting correct datas, +/- 1 meter.

If anyone of you knows anything about this issue I will appreciate answer.

Thanks and greetings!
