Hardwiring an Automotive Device Directly to a 12-Volt Power Source

It is not recommended to hardwire Garmin automotive products to a 12-volt power source unless using a specifically-designed, Garmin-made accessory with a compatible device. Hardwiring a device in any other way may cause damage. Damage incurred in this way is not covered under warranty.

• Concerns of using other power cables (outside of getting enough power) are that traffic may not work, and the cable may not be capable of providing a clean power signal to the device. This could affect the overall performance for all features to work. 
• When hard-wiring a device to a vehicle's battery, the device may constantly be drawing and draining power from the vehicle.
• If a device is not covered by the options above, it should never be hardwired under any circumstances.
