Navigation update

[Big chief]

Well let me say thank you ahead of time, thank you for all the advice and help, but now is there a way to update the nav system on a 2018 street glide without having to go to the Harley shop and having them do it?

You can do it yourself with some perseverance.

Personally I think the onboard navigation sucks and I would spend my money to something else. FI buy a CarPlay dongle and a jumper and use your phone's navigation.
