Replacing an OE audio unit in some modern vehicles can lead to some nasty suprises - one of these is the loss of the OE audible parking tones.....
Advances in CAN Bus technology have enabled manufacturers to use the vehicle audio system for more than just entertainment. More and more vehicle types are now equipped with standard parking sensor systems that deliver obstacle proximity information to the audio unit using the vehicle CAN Bus. The audio unit presents this information using audible tones via the vehicle speakers.
The CANM8-NAVTONE interface reads proximity information direct from the vehicle CAN Bus and produces proximity tones via a tiny, hide-away Piezo sounder, as a substitute for the audible tones originally generated by the OE audio unit.
The NAVTONE interface is ideal for installation when the OE audio unit is to be replaced by an afternarket AV or Navigation system. In addition to the substitute parking sensor tones, the interface also provides the control outputs required to install the replacement audio unit, derived direct from the CAN Bus system.
The CANM8-NAVTONE is supplied with a universal wire-in harness. Alternative 'Plug & Play' harnesses are available seperately. The interface wiring is connected as below:
RED 12v+ Permanent Supply
BLACK 0V (Ground)
WHITE CAN HI
BLUE CAN LO
PURPLE 12v+ 'Ignition On' Output
ORANGE 12v+ 'Illumination On' Output
BROWN 12v+ 'Reverse Selected' Output
PINK 0v 'Park Brake On' Output ***
GREEN 12v+ Speed Pulse Output
YELLOW Sounder Control Output
*** On some vehicles, this wire is also used for sounder control.
The CANM8-NAVTONE Interface is compatible with the vehicles listed below. The interface automatically identifies the vehicle type via the CAN Bus, no installer programming is required.
- BMW : 1 Series (E87) - 3 Series (E90 / E91 / E92) - 5 Series (E60 / E61 / E63) ***
- Citroen : C4 - C8
- Land Rover : Freelander 2 ***
- Peugeot : 207 - 307 - 308 - 807
- Volvo : V70 - XC70 - XC90
*** Vehicles with front and rear sensors will require an additional sounder - available seperately.
