Most of our kits offer 3 bypasses; Parking Brake, Speed Sensor and Reversing Camera. These bypasses are often referred to as Nav hacks, unlocks or overrides.So what are they and what’s the big deal?

Speed Sensor Bypass

This fools the AV unit into thinking the car isn’t moving.

Why is this important? Well, because many of the options such as the phone keypad and entering a street address are disabled when the car is moving >5mph. This means a passenger can't enter an address for you as is possible with many other brands of vehicles.

A common question is “why can’t this be bypassed permanently?” and there is a very good reason. The downside of the speed bypass is related to Satellite Navigation. While the speed sensor bypass is activated the Navigation current location will become frozen or very slow to update. Basically, the bypass tells the AV unit that the car isn't moving (speed=0) and then the Navigation System, being a little too smart for its own good says; if the car isn’t moving then why bother to update the car's location (even though the satellite location would be correct).

When you turn the speed bypass off it may take a few seconds (15-30) to correct the location, but it will catch up. The car plots the location based on two things, the GPS signal and the speed and direction of the car. What happens is it will start to update the location based on the speed input alone but the next time it checks the GPS signal it will correct the location.

 

Parking Brake Bypass

This fools the AV unit to think that the parking brake is on even when it isn’t.  

Why is this important? Well, without this bypass the AV unit will not display a video feed on the screen unless the parking brake is on. We use this on the GT-R kits for viewing the front camera while parking.

While this modification (when combined with Speed Bypass) technically also permits a DVD or other video source to be played while driving (Video in motion/VIM/AV Hack), this should not be used by the driver, that is not our intention and we take no responsibility for any misuse of this modification.

Reversing Camera

This bypass or override allows you to view the rear camera without having to engage reverse. The rear camera will still come on when you engage reverse, just like before.

A common question is “are there are any side effects to the reversing camera override?” and the answer is no. It doesn’t make the reversing lights turn on or the annoying reversing beeps or anything like that. It simply displays the rear camera.
