I wonder if it's an issue with the amount of power that the USB port provides? IIRC, there have been general USB issues related to that with some of the M1 Macs. You might try using a powered USB hub and see if that makes a difference.
SOLVED!! Thank You Boyd!
My son-in-law gave me the following Dynex USB 2.0 hub along with the power adapter. This along with a USB-C to Mini-B Belkin cord and the oem Garmin cord did the trick. I did tests with the power adapter with and without it which worked either way. I'll probably just use the power from the MacBook Pro M1 making it one less cord to plug in.
This particular hub has been discontinued but, there are a few of these on eBay. I would say any 2.0 hub will do the trick just as long as it has 480Mbps for data.
I'm extremely happy with this getting me up and going but, I still feel the same about Garmin. They really need to get their act together and catch up with today's technology when it comes to Mac's. Even the newer units for example; Zumo XT and GarminDrive units are giving people fits as well.
Although not on that list, my 595LM is and has been checked on MTP Auto Detect sine day one. I did try the others with all three not being recognized during tests "without" this old 2.0 USB hub.
Anyway, I whined enough about Garmin.......
I'd like to add, I couldn't upload my pic's along with a couple links for some reason
Once again, Thanks for your help, I sincerely appreciate it. Hopefully, this thread will help others that found themselves in the same jam as I was.
