Nuvi 2557LMT - Garmin Express not being found on multiple devices

I just got the 2557LMT from Garmin and on a Win 8 and Win 7 machine Garmin Express it is not being finding the device using the equipment that came in the box. Ironically I cannot find the 2557LMT on your support section of your site either. I need to get this resolved or this is going back to Amazon.

On a side not your software has always been a hassle and the dev team involved should really figure out how to get things straight on their end.

Also this ended up on the mac thread no sure why, PLEASE HELP ASAP or this is going back to Amazon today

Please try the troubleshooting below:
1. Ensure that the device is turned on when you have it connected. The Garmin device should show a picture of a Garmin connected to a computer tower.
2. Avoid connecting the device through any sort of USB hub or extender. This includes connections through a monitor or keyboard that may have extra USB ports.
3. If you are on a desktop computer, please plug the Garmin into the back of your computer tower. The rear USB ports on a desktop typically provide a more reliable connection and power source.
4. Unplug any additional USB devices (such as printers) that are connected to your computer via USB.
5. Make sure the cable you are using is a Garmin branded cable and/or a cable packaged as a data transfer cable.
6. Try using a different USB cable to connect the device.
7. Try using a different USB port on the computer.
8. Unplug the device, and then reboot the computer. Try reconnecting the device after the computer has fully restarted.
9. Try connecting the device to a different computer. If it is detected properly by the 2nd computer, the issue is likely related to your 1st computer and its hardware or software configuration.
10. If you are using any virtual machine software on your computer please close it or designate your USB port to allow for the Garmin to have a connection to the original running operating system.
11. Ensure that you are directly connecting the USB cable to the device itself and not through the devices mount / clip.
12. Try to take your device out of Media Transfer Protocol Mode (See Steps Below).


Media Transfer Mode to Mass-Storage Mode:
1. Start NUVI by itself and go to Volume Screen.
2. Press the upper right hand corner of screen for 10 seconds.
3. The Developers Screen will pop up
4. Scroll down to MTP SETTINGS
5. Change from AUTO DETECT to MASS STORAGE
6. Shut down the NUVI and hookup it up to the USB cable which should be attached to your computer.
7. Startup the NUVI and it should recognize it is hooked up to the computer.

Because that's where you posted it. If the above advice doesn't help this FAQ may add a few other pointers http://support.garmin.com/support/searchSupport/case.faces?caseId=%7Be908ee90-c6c1-11e1-dcef-000000000000%7D

Note in almost all cases the problem is with the PC, so it should be resolvable. It's always possible that you have a faulty device/cable but that is rarer, but given that you've tried 2 computers it is a possibility.

One question, are both PCs working over wifi? If so try cabling directly to the router/modem.
