You're looking at the newest in technology that is programmed down to the thousandth of a second for EXTREME accuracy. DO not be fooled into thinking that the old relay trick, or just permanently grounding the parking brake wire will work anymore. Aftermarket radios are getting harder and harder to bypass and CANNOT BE DONE WITH A SIMPLE RELAY. With this new bypass, timing is EVERYTHING!!! Several seconds of delay and multiple ground pulses at the rights points in time are needed in order to accurately bypass the parking brake feature of some of the most complicated DVD and Navigation units. WARNING: It is both ILLEGAL and DANGEROUS to watch videos from the front seat while vehicle is in motion. This product is for offroad and show use only and is not intended to be used otherwise.

• 5 Minute install (3 Wires to connect)
• Pre-Programmed to provide Multiple Ground Pulses (No previous install experience required)
• Fully automatic (Turns on automatically when the radio is powered on)
• Ultra slim design. SMALLEST ON AMAZON! Guaranteed to Work!
• WARNING: This product is for show, off-road, and retail display use only. It is dangerous and in most states considered to be illegal to watch video from the front seat of a moving vehicle. Check local laws.
