Hi Chanaka Mahesh Igalawithana,
Thanks for your post in Microsoft Community.
I understand you are having issues with Windows not being able to transfer files to GPS using Bluetooth.
From your description, you can send the file to your Huawei phone smoothly, which means Windows is working fine. But Windows can't send to GPS, which is really a bit weird.
You can try disconnecting and removing Windows from the GPS, then pairing and reconnecting the device to see if the file transfer is successful.
We need to go through a series of steps to find the real cause of the problem. If the above steps do not solve your problem, please let me know and I will continue to assist you with the problem.
