You have fitted your shining new android headunit, got it all set-up correctly for google, downloaded some apps and tested the sounds. All good, maybe there where a few stumbles along the way but you have overcome the obstacles and now it is time to test it on the open road. Everything is great, except on the return home you notice the ‘beep beep’ of the parking assistance sensors are silent.
Silence from the parking aids
Your original factory headunit had some part in the parking sensor aid system fitted to the car. The beep beep came from the speakers via the factory headunit via a manufacturer BUS and your new android headunit doesn’t speak, can’t speak or just refuses to speak CAN BUS.
The simple solution is to use the reversing camera feature built into all android headunits. The android headunits are often supplied with a ‘free gift’ of a reversing camera. The camera may only be for testing purposes to prove that part of the android headunit is working and a better quality or vehicle model specific custom fit reversing camera can be fitted. There are even some ‘birds eye style’ 360° camera systems that do more than any ‘beep beep’ backup system could dream of. The android headunit automatic switching reversing camera removes the need for the factory back-up reversing system and gives it a kick of an upgrade at the same time.
CAN BUS has been mentioned. With a CAN compatible Android headunit it is possible to tap into the CAN BUS of the vehicles with the correct adaptor. Then there is a configuration in the android headunit settings (possibly protected by a PIN) to enable the correct features to enable the beeping parking aid sensors. There are may variables and you won’t have CAN BUS options or an adaptor with a universal headunit, they are more common with a custom fit. If you can’t find the settings then you may need to reach out to the vendor for assistance.
BUT, and it’s a big BUT
Just fit the camera upgrade.
Be it a simple reversing camera, one with trajectory tracking, a fully featured 360° or a custom fit reversing camera, you will be using the android headunit to fulfil it’s destiny of helping you park safely and avoid any headaches with android headunit settings or manufacturer CAN bus system integration.
