Push the Nav button to turn it off (I think) or push the FM button to put it to FM mode. No time for me to look right now but if you don't have your NAV manual, here's a link. Starts on page 53. Looks like pushing RAD may allow for radio even in NAV mode. Lot's of language about interference etc. Pretty sure it has to do with being in NAV mode.


Hope it works

Edited: Here's the link to the page on the forum where you can access the NAV users manual.
