Bob,
Two suggestions:
1) The latest update from their email address. Here is the link and instructions.
https://we.tl/t-23zkUzVEZ1
How to update:
1. Please download and unzip the software, Format USB stick to FAT32,copy all the files(not folder) to USB stick. Please note: You only need to unzip for one time.
2. Plug the stick into USB port, system will detect it and update automatically.
3. When you see "success" in green color on the screen bottom, it means update successfully, then unplug the usb stick.
2) Download the alternate interface that was suggested to me from someone on this forum when I 1st got my unit. I FAR prefer it to the OEM one. For the life of me, I cannot find the name ('Launcher', possibly), but here is a pic of it.
