I am running MacOS 10.11.6 on my iMac. When trying to update my maps on my nevi 255W, the device is not recognized by the computer. I am using a brand new cable (working because my nevi is charging) plugged directly into a USB port on the computer, Does anyone have any suggestions?

Hey Honeycutt,
Did you ever get yours to power up?
I have the one that my dad used to use before he passed. I don’t know anything about it, but want to give it to one of my bosses. It was telling me about a missing system software; but now it won’t even power up.

Both my Windows 7 and Windows 10 computers detect my Nuvi 255w just fine, but Garmin Express doesn’t recognize it on either computer.
I’ve uninstalled Garmin Express, reinstalled it on both computers, and same thing happens - Windows sees the Nuvi just fine, but Garmin Express sucks… keeps searching when I try to add it on either machine. Never finds it. Tried every USB port. Nothing works.

I have a power issue that seems to be common. Plug in nuvi to charge. After overnight charge, nuvi still seems to be dead. Open up nuvi and unplug the battery. Plug battery in again, "low and behold" FULL charge! Either Garmin is installing crap sensors or flakey software. I'm not impressed as I have to do this every time I charge the device.

I updated the software yesterday now it’s saying Software missing on the screen.
