I received an email from Nikos P. this morning asking:
hello my friend i need to enable back camera rotate i place a cam and its not turn back when i put reverse
I’m not sure I understood his question, but it sounded like he added a second camera without a video switcher, so it took priority over the reverse camera. I remembered coming across a solution months ago that was developed for our Infotainment Systems by a small company in Russia (with which I have no affiliation with, other than sending them an email asking if this would work on the MX-5 and the 124 Spider – it apparently does, as they’ve been added to the list of intended vehicles) which allows you to control the various camera functions using the DSC switch (or an independent switch if you prefer).
It appears that their various electronic products (Wireless screen mirroring, DVD and TV controllers, etc) are well thought-out and fabricated nicely, using wiring connectors that mate with the appropriate OEM connectors in the vehicle to minimize splicing, and the Front View Camera Controller seems like it is fairly priced at $110, which includes shipping. I am presenting this, to hopefully answer Nikos’ question; in case others might also find it helpful; or in case others might wish to purchase this solution for even greater utilization of the 7″ screen.
If your car has a rear-view camera installed, then by adding a controller, it will make it possible to also install and view the output of a front view camera as well
ACTIVATION: The choice of modes is possible by pressing and holding the “DSC” button for more than 1 second. Each press switches the OFF – AUTO – ON
(it seems that more recently, this was changed to short pressing the “INFO” button on the steering wheel instead)
- OFF. (front view camera disabled)
- AUTOMATIC. When the vehicle is moving forward at a speed of no more than 7 km / h, the image from the front view camera is displayed.
- ON. In this mode, the image from the front view camera is constantly displayed.
ALL ORIGINAL FUNCTIONS OF THE MAZDA/FIAT CMU WILL BE RETAINED!
Instructions for installation and implementation (includes wiring diagram).
CMU ~ Isolator
⇓ Chances are very good that the isolator that slides onto the tab at the rear of the CMU will detach itself while sliding the CMU out of the DIN slot. Just be aware of this as you are assembling the CMU back into position.
