Question about Garmin zumo 550 GPS Receiver
After a few months of disuse, th unit will not turn on despite charging. No response from any button
Have you also held the power on button for a couple of minutes, with the battery installed, and without the battery installed. There is an issue with the garmin dying, some cases a new battery helps, other cases, just leave the battery to charge for several hours, worst case is that you have to ship it to Garmin. I had a couple of Dead Zumo, however, removing the battery for several minutes, putting it back and clipping the zumo in the car holder did the trick for me. I also have a spare battery and allen wrench, just in case...

My Zumo 550 went dead while riding. Simply removing and replacing the battery was enough to bring it back to life.

I had the same problem and by connecting the Garmin to a computer using the USB cable that comes with the device, you will be able to immediately get the power back. Leave it connected so that it can recharge the battery completely and it should be working fine afterwards. It happens sometimes when the battery is completely dead and so it needs to be connected to an electrical device to regain its optimal charge. I hope this can help!

I took the (fully charged) battery out, replaced it: still dead. Then I hooked it up to my computer (usb cable), and it immediately turned on and went into the 'mass storage mode' (as it should).
After disconnecting the Zumo (ejected the drive (Mac), then unplugged), it works again just like before it faked death.
I understand that you don't necessarily carry a computer everywhere you go, but on longer trips I carry an A/C power supply cord ('Garmin Switching Power Supply', model PSC05R-050A1). This should do to jump-start the Zumo,since it uses the same port on the device as the usb. I have yet to replicate the problem and confirm this method with this power supply.
This of course requires an electrical outlet you have to find and 'borrow' for a few seconds.
If you want to be even more independent, and your bike has a provision for a cigarette lighter style power outlet, get a 12V to 120V transformer: it's under $15, gives you a regular electric plug, and is really handy in a pinch.

If this becomes a recurring problem, but the battery removal fix works for you, you may want to take the battery mounting screw and cut a slot in the head. this will allow you to use a regular screwdriver instead of carrying around a special allen (hex) wrench/key. i put a tiny bit of wd-40 (lubricant) on the face of the screw in my unit, since cutting the slot takes off the anti corrosion finish.

I took the battery out and put it on the bike mount without the battery installed and the Zumo finally turned on. I put the battery back in and now it seems to be working ok.
