Rear view mirror with compass!
 

2024 Edit:


Since I'm getting bombarded with emails now, this thread needs an update.



The source mirrors for the conversion have become very scarce, so I stopped searching for them and stopped doing the conversions *years* ago. As of 4/29/24 I have a couple of adapters remaining, that's all.

After many months of trial and error, and lots of bad ebay purchases, I've come up with a plug-and-play option for a rear view mirror with a compass, with the correct display color to match the C4 dash illumination. The mirror also retains the map lights, and the courtesy light function of the map lights when the door opens. I also added an orange LED for the ambient light on the console, just like the stock mirror. Mirror also has electrochromic auto-dimming.

I have also developed a plug-and-play harness, to adapt the mirror right into the stock C4 wiring, without the end user needing to cut a single wire.

And here's the excellent adapters that Carter machined up for me! Really nice workmanship on these pieces!

I also can now make the same mirror with an outside temperature readout as well, great for the guys with manual AC without the temperature display in the dash! Pricing not finalized for this option yet, but I expect it to come in around $100 more than the compass-only mirror.

Im in how do I buy one Andrew? Great idea

Re: Rear view mirror with compass!
 

As for the mounting issue, I'm working on that too. Carter is looking over some adapters I've come up with, to see if we can produce a small batch at a reasonable cost per unit. This would allow mounting to the stock location on the windshield header, without having to glue a button to the windshield.

Daryll, PM sent.

Awesome:cheers:

I assume the power button is the on off feature for the compass? Obviously the north arrow bottom is for adjusting.

COOL.. I would like one like that but with the temperature (remember I have a C60 car)

Re: Rear view mirror with compass!
 

Hmm, I forgot about you C60 guys. Let me see what I can find, I might be able to find an existing mirror to make that work too. The temp sensor wiring would have to be run separately, since the stock wiring obviously doesn't provide for that.

Jeff, after a cursory search, far as I can tell so far, the options for including temp with compass will require losing the map lights / courtesy lights function, and may also require having nonfunctional OnStar buttons on the mirror.

There is an option that has map lights, and a display for compass/temp below the mirror, like this one:

It's a bit pricey, but it may be the only way to get all the functionality.

Mirrors with comp/temp are easy to find, if you don't care about the map lights. I could modify one of those for you (change display color+add ambient LED) if you wanted.

sorry you lost me at auto dimming. I hate that

Re: Rear view mirror with compass!
 

There is a button to turn that off, you know :cheers:
