Dear MyFlow,

Thank you for the detailed information provided, as well as for the translation of the user manual.

We are software developers of the GPS-Trace platform. Unfortunately, we cannot help in this situation, since the problem is in the device itself.
We hope you will be able to resolve this issue with the manufacturer.

If you have any further questions or concerns, please do not hesitate to contact us. We will be happy to assist you in any way we can.
