Is this worth picking up as a backup to my 3597?
https://www.amazon.com/gp/product/B07VRD7YYM
Am I missing anything? Currently I use a second 3597 & my iQue as backups but 3597 has a problem with the SD slot and iQue mostly is for overseas travel. It handles NZ maps real well.

Is this really the intent of the "extra" pin?
Amazon took over 3 weeks but did supply a new USB cable that transfer data and charges. At first the CS Rep wanted to send me a Garmin OEM cable from Amazon UK. She sent a message back that the seller wouldn't ship to US so offered an Amazon branded cable. All works now.
There are as mentioned here two types of USB cables; power only and power + data. But beyond that, some “generic” cables don’t work well with Garmins’ because the OEM cable for many models incorporates a resistor between pins 4 & 5. That enables the device to detect what it thinks is a genuine OEM cable. See http://cooperbaker.com/home/other/garmin%20usb/ for one type of hack that overcomes the issue.
Reminds me of one of my favorite quotes that I've likely repeated here at poi-factory: "Standards are wonderful and the best part is that there are so many to choose from". I've never read any of the USB specs. Is this really the intent of the "extra" pin?
5th pin is for ID

You may be referring to the 5 pin USB connector defined by the On-The-Go standard (OTG). The additional pin added to the conventional USB port is the ID pin added to the 4th electrical pin, and allow to recognize the device. Here is the resulting electrical setup of the pins:
VDD (+5V)
D- (Data-)
D+ (Data+)
ID (ID)
GND (Ground)
As compared to other 4-pins USB devices, where there is no ID pin, the advantage is to be able to distinguish the host device from slave devices.

Thank you!!
