GR Yaris Retrofit Yaris Cross Headunit - it can be done!

Hi folks, looking at doing this swap myself, been reading up on it.

The one open question seems to be the DCM, and therefor SOS / MyT functionality. Not a deal-breaker for me, but be nice to get everything working.

So the factory DCM (86740-0D031) won't connect to the new Smart Connect head unit is that correct? As the Smart Connect has the flat 5-pin connector which the old DCM doesn't? But all of the old DCM's cables do have sockets in the new Smart Connect, so has someone tried this?

Or what about leaving the Smart Connect's DCM (86740-YP010) connected? Anyone tried that? Does that work if you just enroll it into the MyT app as a new car?

Drop me a PM bud. I have the newer DCM on mine and will try it out at some point!
 
Has anyone got any tips on how to actually do this swap? I had a look and can't work out how to get the bottom part of the plastic surround off to get the unit out, and then it looks like it's held in with allen bolts with epoxy over them? Is this a no-tools job or more difficult?

Hello, I have semi-successfully retrofitted 9” 4button Harman headunit to Toyota Auris. I have a few questions, since I have encountered similar problems.
- Is there a solution for the headunit not switching to night mode? I can see that it gets the signal from the car when it switches from DRLs to full driving lights since the 4 buttons are backlit. Do we know what is the issue here? Is it the clock that controls the night mode?

Thanks to this thread i changed my headunit too!
Everything the original unit could do, is working fine and even better. CarPlay on a much nicer screen and wirelessly is just perfect.
The clock not working does not bother me and i could even connect the system with my hotspot and update the firmware easily.
10/10 would do again!

Hey GR_Jonas,

Are the vehicle settings still available after the upgrade?

Thanks.

I've just done this in mine and I noticed a few things:

1. Much better sound then the one that comes with the car.

2. However, even if I put the volume on max (30) it is still very low. Low enough so it's hard to hear while driving. Did anyone get that?

3. When I'm approaching or passing a toll checkpoint the connection between the unit and the AA will be momentarily interrupted (the music) and in some cases the AA will disconnect altogether.
I'm in Australia. I'm not sure what kind of sorcery our tolls use.

Anyways, not good enough for me I will be selling and start looking for something else.
 
Yes the volume is quite low even turned up to 30. Installing the Beat Sonic ENA3T3 amplifier has resolved this issue for me and made a vast improvement. Also have after market door speakers and tweeters installed but still sounded low until the amplifier was installed.
