I’m looking for technical help or recommendations on: __Infotainment System
My infotainment system had a threw a wobbler today and nearly caused me to reverse into my drive wall! When I put the car into reverse gear and started reversing the reverse looked clear and if it wasn’t for the rear proximity sensors screaming at me I would have reversed into the drive wall. It wasn’t until I took a really good look that I realised something was amiss. The screen for the rear camera was still showing a view of the B&Q carpark that I had just returned from I took the car out of reverse gear and then re-engaged reverse gear and the B&Q car park was still there! Switched engine off and on again and engaged reverse gear and B&Q carpark still there. Had to do a full factory reset, losing all my settings and bluetooth connectivity to my phone Has anybody else experienced this and know what might have caused it?
Never heard of that one. However to do a reset the easy way is to hold down Back Arrow, Mute & Nav buttons together on the centre console panel. After around 10 seconds the screen will go blank and the unit will reboot. Shouldn’t lose any settings, all it changes is switching to FM source. Will usually clear any hiccups. The Mazda equivalent of Control, Alt, Delete.
Not a full factory reset just a reboot but the best thing to try first. Has the same effect as disconnecting the battery but without upsetting ABS, ECU and every other widget and gizmo on the car.
Has to be a problem with the MZD unit. The camera itself whether OEM Mazda or after market is an analogue camera as is the input to the MZD. The image is only converted to digital within the MZD. Somehow the processing has frozen the image.
I fitted my own version (same idea as Roadie’s, and cost me £35 for all the bits) in our 2016 Mazda3, which has the same Infotainment system and wires in the loom all the way to the hatchback lid, and so far, touch wood, it has been reliable.
Wife’s CX is GT sport, so OE camera. In general the MZD seems very unstable, especially when integrating with CarPlay.
The latest glitch is intermittent no spoken nav instructions, it just mutes the radio or whatever, then silence, even with the volume control on max and not muted.
I’ll try the reset suggestion above, or it’s back to Mazda for about the 5th time…
The MZD has a digital processor, and part of that is a field store where the image is converted from interlaced analogue video to the progressive digital display.
The store will hold data as long as it is not reused nor reset and the power to the MZD remains uninterrupted.
If it was not receiving something from the camera it would not try to show the image.
So it is thinking about it, but not succeeding, merely fetching what was last in the store.
This might happen if the camera is no longer on frequency or the signal is low level so the MZD cannot see the syncs properly.
I think a bad connection somewhere might be the main culprit. Dig out the Servisol Super 10.
The only times I’ve had trouble with the Nav system freezing is when I’ve used a carpark that is next to the District Line depot and left the car near a row of transformers (?) there. I have to drive away, stop and do a re-set before things go back to normal. Cause or co-incidence? I wouldn’t like to say.
Didn’t want to start a new thread, but as it’s an infotainment system ‘wobble’, I’ll put it here.
I have a 2020 ND2 RF GT Sport Tech (such a long name for a small car)
A few weeks ago I started to randomly get an “invalid SD card” message. Not a big thing as I use Waze anyway, and a quick eject and pushing it back in clears it.
Today whilst enjoying the scenery in the M25, the Infotainment system seemed to reboot. Had a black screen with the Mazda logo and a circling thingy letting me know it was ‘doing something’.
When it came back to life, I had no power on the top USB socket so my plugged in phone stopped charging and lost its Android Auto connection to the Infotainment system.
I stopped at a service station, switched off the car and started it again (universal IT fix), Infotainment system booted fine, but I still no power from the top USB - bottom one was fine, so that ruled out the phone and the cable.
Continued on my journey incident free, but without Waze.
Got to my destination and after a couple of hours, returned to the car and everything was now fine. Power from top USB and Android Auto now working.
Very odd, and i had already started thinking of replacing the USB module with a wireless one if this had indeed died.
My gut feeling is it’s a one-off, but the SD card giving random errors makes me think not.
Guess I’ll see if it reoccurs. Just wondered if anyone else had had this?
Sort of. When I bought my 2016 ND Sport Recaro the SD card with the nav info on it turned out to be bad and it caused all sorts of glitches with the infotainment. Removing the SD card until a new one was sourced stopped the infotainment misbehaving so try leaving your SD card out for a while.
I took the car out of reverse gear and then re-engaged reverse gear and the B&Q car park was still there! Switched engine off and on again and engaged reverse gear and B&Q carpark still there. Had to do a full factory reset, losing all my settings and bluetooth connectivity to my phone 
Has anybody else experienced this and know what might have caused it?
I should have realised!!
