Updating NAV on Wrangler Unlimited Sahara 2017. Where do I find my “product serial number” for Garmin uConnect online?

Hi folks. Trying up update my NAV. Following a YouTube video. One step is to enter my “product serial number” on Garmin uConnect online.

Looks to be 20 digits (letters and numbers combo). Format is XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

I have no clue where I would find this number. Anyone know what I’m talking about? Thanks!

SOLVED: Can’t just use any old USB. Have to order one for $100 from Chrysler group.navigation.com
