If your automotive device freezes up or will not power on, the device may need a soft reset.
To power the device OFF with a soft reset:
Press and hold the power button or hold the power switch in the on position for 8-10 seconds.
To power the device ON with a soft reset:
In some cases, the device may even appear to be dead and refuse to power on from external power. This can be corrected by performing the soft reset while the device is connected to a power source with a USB cable, vehicle power cable, or an AC adapter.
The above soft reset steps are applicable to all automotive devices except as noted below:
nuvi 300 & 600 series:
Press and hold the reset button for 10-15 seconds (the reset button is located under the antenna on the back of the device)
nuvi 500, 800, & 805 series:
Remove and reinsert battery
nuvi 5000 soft reset:
Unplug from power and then reconnect device
zumo 400 & 500 series:
Hold the power button AND the zoom (+) button for 8-10 seconds (or do the following:)
zumo series (except zumo 300 series):
The device will now power on. Because the battery may deplete while the device is locked up, it is ideal to connect the device to power to allow it time to charge.
Once the soft reset is successful, it is recommended that you update the software on the device. Step-by-step instructions for this process can be found in the FAQ article below:
