how do I adjust the voice prompt volume in the navigation with out adjust the radio volume?

You need to study your owners manual. No offense, but not many of us have a brand new Equinox to answer you.

I did check the owners manual, as well as the "Getting to know your Equinox" it seems well hidden in the little book... By the way, maybe leasing is a good option for you. I get a new one every 2 years .

You would normally just control it with your regular volume control you use on your Radio.

Destination...voice prompt...navigation volume. It is difficult to find. Gotta love the smart ass answers! ;)

We don't have book with us

Thanks We are on Dc Belt Way

You have to wait until the navigation system is talking and then use the radio knob to adjust the volume

If you hear her/him speak, turn the volume up/ down. The blue line is radio, red line is navigation.
