How to check card ID in eTrex 30? It has non-touch screen...

On any of the 7xx series here's what you do.

1. boot it up and hold your finger on the battery icon for 5-10 secs and it will flip to the maint mode screens
2. on the lower right corner of the screen hit the NEXT button and you'll cycle to the "Data Card Test Page"
3. your SD card serial number will be spelled out clearly indicated on the upper left of the screen

If you have booted in the car or a home charger (external power) the battery Icon will not appear. No problem, to get to the maint screens....
1. go to the "where to" screen
2. hold the screen just to the left of the clock (where the battery icon would normally be) for 5-10 sec and it will flip to the maint mode screens. If you're sloppy about where you press, you'll flip to either the to the Map or Clock screens, depending on where you fat fingered it.

It all works fine... I do it all the time on a 755T and others.

Also in some models you need to hold down the battery icon not the clock

Hope that helps

FYI - not a SD cards have a 10 digit serial number. I've used a few with less digits (as seen by the Nuvi). I've never seen more than 10 digits.

I think the number of digits depends on the manufacturer. Less numbers i more frequent in Micro-SD cards.

FYI - Not weird at all

6 digits is OK if that's what the Nuvi data card screen says. Some cards have a shorter number. Some folks assume it 10 digits because
most of SD serial are actually 10 digits and the expectation is that it's 10 digits because every Nuvi (I've ever seen) has a 10 digit SN (unit ID).

This may sound silly but a "sure" way to find it is put it in someone else Nuvi and check it.

I've never seen a reliable alternative method.

I installed this plugin, and after interesting microSD card into computer, on this website appears "An SD Card" phrase but nothing else happens...

There is screenshoot:
