Most of the Dension products connect to the electrical or optical system of the car they are installed to. Such connection however does not alter the electrical system of the vehicle, the connection is not materially different then connecting other aftermarket accessories like phone kits, or other entertainment electronics. Dension products are designed to work with the vehicle’s electronic system through the existing factory built original interfaces of that system.
We strongly recommend to have your device installed by a qualified car electronics technician. Dension does not warrant any installation work or assume liability for any damage caused due to negligence, improper installation or operation.
