Roav VIVA by Anker Alexa-Enabled 2-Port USB Car Charger

I am interested in purchasing this as a gift. Can someone tell me if the recipient would need to subscribe to a service such as Amazon Prime to use the car navigation, etc. Right now, all they have is a general Amazon account.
Thanks for your help!

This item, right?

You do not need a Prime account to use Alexa. You do need a Prime account for Prime Music and other premium features. I do not believe navigation is considered a premium feature.
