Thread: Garmin Maps expiration Date

Thanks, that sound encouraging! Turns out that holding the power button is all that is needed to enter that mode. I still have all of my previous updates so shouldn't have a problem. I'll give it a try tomorrow and report back on progress. Thank you all for your help!
