If you have a vehicle that is not being used regularly and experience a flat battery, you may wish to have Sleep Mode applied to the GPS unit.
Sleep mode will put your GPS unit to "sleep" while it is stationary, limiting the draw on the battery. The GPS unit will "wake up" from Sleep Mode the next time there is an event to report on, such as the ignition is turned on or the vehicle doors opened.
A flat battery can occur in a low use vehicle because the battery has no opportunity to recharge while it is being driven. With the added power draw from the GPS unit, this can result in a battery that is never recharged but continuously with a power draw.
If you have a low use vehicle you would like Sleep Mode applied to, please contact the support team here, outlining the details of the vehicle you would like this applied to.
