CN10-01202B GPS signal problem

[showman]

Hello,

I bought CN10-01202B unit from Ebay. Everything else works fine but GPS-signal is very unstable. I have tried IGo, Sygic, Here... and it's not program problem. What I should to try that I get stable GPS-signal? New firmware or something else?
Here are some details:

Hi,
you can do as follows:
1.check whether connect the GPS antenna tightly.
2.try to place the antenna on other place such as on the right corner of the windshield.

Hi thanks for your answer.

1. I checked connect and antenna connect is tightly closed
2. GPS antenna is middle of dashboard. I tried different places and that's not help

Pumpkin found 9-12 GPS satellites but signal is very unstable. With CLONASS there is same problem too (found only 5 satellites).

Hi,
the unit can find 9-12 GPS satellites means that the reception is OK.What do you mean when you said the signal is very unstable?
Could you show me an video about this?

Hi,

I mean that it's same what navigation program I use (Sygic, Here, iGo, Google Map, Wase), map freeze and no speedometer. This happen many times per minute or sometimes it takes over two minutes to start update map and speedometer. In a city, navigation is totally useless.

Hi，
so you can flash the following firmware.

Download and unzip the files on the root content of one sd card.Then enter into settings - extra settings - system update.
Hope your feeddback.

Hello Jammy,

Now it seems to work fine. Problem appear only if I listen Spotify via Blutooth in a same time when I use navigation.
