Unstable connection issue while Google navigation is in use

[kojikunitake]

Hello,
First of all, I have to say thank you very much for this project!
I have the official retrofitted MINI (BMW) HUD, but I could not use it for a while because the support by Garmin is ended a few years ago.
So, this solution is perfect for me.

Just tried the GoogleMaps HUD, and it did found and paired with my HUD.
However, when I started the navigation using Google Map, the connection to HUD got unstable and the communication between the app and HUD did not work well.

I will try to explain and put the details as much as possible, but please let me know if you need any other information.
It might be related to the device environment of my mobile, so I will put the details of my mobile as well just in case.

[Version of the software]

GoogleMaps HUD v0.8.9

[HUD model]

MINI HUD (retrofitted at MINI dealer), which is the same model as BMW HUD.
The connection to the device is made by WiFi, and use the mobile data to get the map data etc.

[Device]

Sony H9436 (Xperia XZ3 dual SIM, European model)
Android 10
Build number: 52.1.A.3.137

[Problem]

When the Google Map navigation is in use, the connection to HUD got unstable and the communication between the app and HUD did not work well.
I have attached the video, hope it helps to understand what I am seeing.

[Actual issue]

In the MAIN tab, Status which indicates the connection to HUD keeps dropping off.
It continuously shows 'BMW HUD connected' for a sec, then changes back to 'HUD disconnected'.
When I see the DEBUG tab, I can find that the notifications are sent every second or so.
The HUD display shows the correct next turn symbol (straight, turn right, etc.), but the distance is always '0'.
Also, it does not show the estimated arrival time.

[Note]

My device is also connected to a smart watch, but the problem did not resolved after disconnecting it by disabling Bluetooth.
