Garmin updating bluetooth firmware garmin nuvi
When I tried to do it again, I got the message that the 670 was already updated,tried to update again,got the message"The update file is corrupted".
But your procedure worked,took a good minute for the flicker and then the Pre-Boot message to disappear,then it started loading some Bluetooth update and then came back to the normal screen.
go to the direct software update link: - Download: Nuvi 660 software update version 4.70 (4.86 MB) as of December 11, 2008 Thank you, thank you for sharing the info on holding power button down.There was a progress bar and after about 2 minutes it was done. I assumed that my device was just completing the BT update cycle.Can't say I've seen this happening after an extended time from when my device was booted up.Updated Bluetooth 3.40 available on Garmin Web Updater for Garmin 7XX series.
Everything seems to work fine but remember you have to pair the phone and the Nuvi again after doing the update.
Hello All, I recently downloaded the Nuvi 660 firmware upgrade from the Garmin site to upgrade to v2.70.
