| Posted by nick99990_0 Nuvi firmware recovering - system software missing Hello All, I recently downloaded the Nuvi 660 firmware upgrade from the Garmin site to upgrade to v2.70. I did this as I read some other comments that the Garmin webupdater application has (in some cases) caused corruption. I ran the firmware update as per the instructions from the Garmin website and two .bin files copied to the unit but the third file (I can't recall the extension) failed to copy with a file in use error. I could not work out a way to recover from this as the upgrade failed (not fully complete) and the only option was to reset the unit via the power button. When the unit came back up again the following error came up on the screen: "system software missing" The Nuvi would not boot! I contacted the local Garmin support rep and I was given the following sequence to recover from this condition: 1. Power off the unit. 2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least). 3. Once the pre boot mode message disappears release the power button and your device will perform some activities to recover from the above problem. Apparently this sequence will only work with the above error. I hope this assists other if they encounter this problem. I still don't know why the firmware upgrade process failed BUT after performing the above sequence I found that the firmware upgrade had actually worked (strange). Regards, Nick. |

| Posted by JW Re Nuvi 660 firmware recovering - system software missing Had the "system software missing" problem after attempting to upgrade software to v2.7 using the web updater. Tried the fix posted by Nick - it works! - many thanks Nick. Strangely when it came back up the v2.7 upgrade had worked for me too. JW |

| Posted by jes327 This Solution Worked Seven Years Later! Nick, I don't know if you'll ever get to read this because you had posted this solution almost 7 seven years ago! I just wanted to say "THANKS" for the solution you posted. It worked for me and saved my GPS! I'd been playing with my Nuvi 660 trying to update the maps on the Garmin website. I have Lifetime Map Updates, but kept getting the mesaage saying my device hadn't have enough memory! It's been a common problem from what I've read. So anyway I started deleting files to hopefully free-up enough memory and, of course, messed-up my Nuvi 660 having deleted too many files. I ended-up formatting the entire device memory using DISKPART from the command prompt in Win 7, but the Garmin Express updater then could no longer recognize my Nuvi, of course. After using your solution - holding down the power button, waiting what seemed like a minute until the Pre-Boot words disapeared then going thru the procedure to set the touch screen to work? - I then noticed my 660 had re-installed some files and these were the files I had needed for the Garmin Express updater to recognize my Nuvi! From there I was able to update the newest maps for North America, two American English TTS voices (Jack and Jill) and one orange sports car :) To install these files within the Garmin Express updater I had to click-on "device" then "advanced". When finally finished all the updates I had only 6.15MB of free-memory available on my 660 and was happy as a pig in poop! I didn't have to go out and buy nor install a media card to get full coverage mapping of North America! Thanks again Nick for your post as it saved me a couple of hundred dollars! |

Good post Nick! New Nuvi units use the following sequence: https://www.gps-data-team.com/pda-gps-navigation/viewtopic.php?t=3605#21160 1. Power on the unit. 2. Go to [Main Menu] -> [Volume Control] 3. Press and HOLD the upper right screen corner for ~ 10 seconds and you will see the hidden set of control options. Cheers |
