I received a used GO600 from my brother in law. I have been trying to update it. MyDrive Connect says I have to install the Navcore update, but every time I try it it just stops updating. It shows that it downloaded the update and is updating the device, but never does anything. I have kept it hooked up overnight and still nothing. I am using a MacBook Pro with OS 10.15. Any ideas? This as screen shot of where it hangs.
