My zumo won't power on

I purchased my Garmin Zumo yesterday as a replacement to a Zumo that was stolen in my car, so this is my second Zumo, I know how it should work. seeing that my insurance company does not offer warranty on replacements, I need to get this fixed ASAP.

It was fine out of the box for one route on the crade in the car, then I took it out of the car. 6 hours later, I got back in my car and hooked the Zumo back into the cradle, only to find it would not power on at all. there should be some battery left to turn on, but it is dead. Just now I hooked it up to my laptop via USB and it all of a sudden gave me a screen with teh Garmin Zumo logo. Now it powers on. would like some help if this is a normal thing, or try and getit replaced.

    same problem. Brand new, hooked up to computer to register it downloaded information, turned off as instructed. now won't turn on. Called Garmin support (25 min. wait) They said to remove battery then put it back.

    Still didn't work. Tech person is sending new battery. I know that is not the problem. I'll end up sending unit back. Total probable time 2 weeks. VERY FRUSTRATED. Big investment, currently worthless

This sometimes happens if the cradle is owered while you connect the zumo...i guess it hits some wrong contacts first and goes bonkers. I'd advise th zumo users to pack a small allen screw bit to unscrew the battery, just in case it freezes or blacks out again....better safe than lost in the middle of nowhere!

I had a similar problem. When it failed, it was in the dash mount cradle, with the power connected. It worked when I shut the car off, but would not power up when I restarted the car. Removed the battery, then reinstalled it. Now back to working normally.

    HI I have Zumo 550 when I first switch it it comes up with can't maps press OK you press OK then starts to work but starts at 1am on the clock and in night time mode after awhile it goes to the right time...

    If your zumo 400 or 500 series will not power on, or performs strangely after powering up, follow the steps (described on the Garmin website) below to perform a soft reset:
    1. Connect the zumo to a power source such as a computer or AC outlet
    2. Hold the zoom (+) and ON buttons at the same time for five seconds
    3. If this does not restore power, remove the battery for five seconds
    4. Place the battery back in the zumo
    The zumo will now power on. Because the battery may deplete while the zumo is locked up, it is ideal to leave the zumo connected to power to allow it time to charge.
    Once the battery has charged, follow the steps on the Garmin site to update the operating software in the zumo. (just copy this link to get there{8576ba20-e948-11dc-d6fc-000000000000} )

    Good luck,

    Zumo 550 randomly shuts down, sometimes won't power up again.

    Commonly happened when playing MP3's using an early version of the firmware. Install the Garmin updater and install the latest firmware and patches.

    My original unit did the same thing.

    GPS is not getting power on the motorcyclen mount.

    If you're sure the power cord is getting power, then the mount has likely failed. Mine has failed 3 times. Replacing the mount will fix the problem as it did on mine. If the unit is less than 1 year from purchase, Garmin will warranty replace it for free. If not, it'll cost you about $85 plus shipping to put a new one on.

    Use the allen wrench to remove the battery. Let stand for 5 minutes and replace the battery. It should start fine. Mine has done this 3 times since I purchased it.
