HomeLink on 2014 Mazda3 s GT?

[KuroHouou]

As most of you who own sGT's have noticed, there is no Homelink mirror as an option. I've talked with the MITO people (the distributors of Gentex mirrors) about the issue. If you'll notice the installation above, you'll see that there are only two wires going into the mirror. On the sGT auto-dimming mirror you have 3. The wire between the red and black is the wire from the rear body control module (RBCM). According to the MITO techs, this turns off the auto-dim when you have the car in reverse so you have a clear view to the back. Neither the auto-dim mirror above, or the Mazda Homelink mirror have this signal built into it. Since all of the other body trims don't have this function in the RBCM, there is no wire to connect. Therefore, if you have bright lights, you'll have a dim view through the mirror when backing up.

The MITO tech people assure me that not attaching that RBCM wire will have no negative effect. Therefore you could get a 50-GENK45AM Gentex mirror and install it with custom wiring. You'll already have an ignition power and ground from the current mirror and you'll just have to tap a full power line for the only other connection you'll need. If you were willing to have the Homelink only run when the ignition is on, you could attach the power wire to both locations. Otherwise, you'll just have to run a power wire from the fuse panel, up the A pillar and into the mirror. Just like the other trims, the mirror might dim when backing up.

Now, I'm still not sure about what happens when you don't attach the RBCM wire, i.e., will you get an error code? Perhaps one of you that knows a Mazda dealer can get an answer to that. Unfortunately, the cheapest I've seen a 50-GENK45AM mirror is $279. If you are going to remove the A-pillar, you'll also need a new clip - but I'm sure that's pretty cheap.

Questions Comments?

Thanks for digging up the info I must say, every car of mine in the last 10 years has had home link.. The fact Mazda put so much tech into this car but forgot homelink is beyond me. Not a deal breaker by any means, just very odd and disappointing.

I don't think there has ever been a need for me to turn off auto-dimming while backing up.
Useless feature if you ask me.
I won't worry about it. Tie it to the ground should be better than let it floating.

just fyi - the current S-GT auto-dimming mirror has 3 wires - ign+, ground, and + in reverse. You will only need to run a constant positive for a homelink mirror - and it's optional - the mirror can work on the current 3 wires but will only function with the ignition on. The problem is the mount. In summary - the S-GT currently has the "+ in reverse" wire that defeats the dimming when you're in reverse.

Instead of purchasing and trying to make the homelink mirror to function & fit the sGT's . Was thinking if it's possible to just install the homelink 5 module on the headliner as a viable alternative?

Hey Rvoll.
So glad you already have your sGT, i've been waiting since september for mine! =(
expected delivery date is mid january for mine.
if your installer can do this for the sGT's with tech package, i'm all game, and can definitely meet you or him, seeing that you're from NJ and i'm from NY...
please keep us posted...can't wait! =)
I definitely would want the homelink integrated into the mirror instead of cutting into the headliner for the homelink 5.
However do you think it's possible the homelink5 will work without issues if i go that route?

thanks again.

rvoll,
please post some picture when you have yours done.
I have a sGT w/o tech package. The garage clicker works fine, but I am very used to HomeLink now on all vehicles I have owned.
No a dealer breaker (since I already bought mine), but it is nice upgrade to have a well-integrated mirror.

One more comment... If any of you have specific questions, let me know as I've done a lot of research on this issue.

Great to hear man.
My car is due for delivery in mid January.
I have the tech package with my sGT, so a longer adapter is definitely needed.
Can't wait to get this done.

Now the next thing to tackle is remote smart with viper's smart start

 

[Young-nyc]

Btw Rvoll, can you explain why the tech package needs a longer mount?
Does the mirror hang lower compared to the non tech package?

Thank you!

 

[Young-nyc]

that's good to know..so the adapter is to solve the clearance issue...great..thanks!

I feel so stupid , I missed this as well. But certainly not a deal breaker for me. My previous car, a Veloster had one, but the extra goodies on the GT compensate for that and more.
