    Hi Guys,
    performed an upgrade over the weekend, i was getting sick of replacing batteries in my garage door opener so I ordered a homelink Auto dimming mirror from the US.

    I use to have auto dimming mirror in my previous car but the calais lacked it. Easy mod that took about 30 Mins.

    Cost under $100 dollars delivered

    Mirror can be bought from here with delivery and cover it was around $83 for me, but i notice postage has since gone up making it around $120

    Wiring - I used a USB 10 Pin header as this fitted it, as finding the connector to match the mirror exactly was impossible, you only need 3 pins

    Pins - I bought new pins but you could simply use the USB cable but i thought it was a bit thin

    Cable - You only need 3 core, i used some 4 core Alarm cable, you can use the USB cable if your comfortable to. 4 Core 14/020 is best but you can do it with this one also and it will work fine. The 14/020 is easier to work with the crimp pins

    Or

    The process is pretty simple to wire up, wiring can be tapped into at the interior roof dome light.
    There is a ground and a 12v accessory feed that powers up when a door is opened or the car is started

    If people are interested ill throw some pics up detailing the pins and wiring.

    All up great mod and works with both our BOL4 Steeline / Boss garage door openers. I have programmed both doors to 2 of the 3 available buttons. For the record my garage transmitter operates on 303Mhz.

    Step 1 - Remove your existing mirror - Using a Torx T20 loosen off your existing mirror and slide upwards towards the top of the screen.

    Step 2 - Get new mirror and mount on to the Wedge - Tighten using the Torx T20

    Step 3 - Make a wiring loom using the below pin outs and 10 pin header

    Step 4 - Using some wire strippers, strip back the wires below from the map light connectors about 3 or 4mm. Join the ACC & 12V to the 12V pin, solder it on, Then join GND to GND. Secure with solder and then wrap in PVC electrical

    Step 5 - Remount your sunglass holder in place

    Step 6 - Program the button by holding down Programmable button 1 & 3 for 20 Seconds. Get your remote transmitter and hold down the button to open your garage and at the same time hold the button on the mirror you want to program that transmitter to, it should flash when it has copied it. Repeat the process and then turn the mirror off. You should be all done now. Test the button works by opening your garage, When you press the button it will light up Red

    Keep an eye out for battery drain. I've seen a few vehicles with aftermarket mirrors and **** hanging off the interior light causing the BCM to stay awake and drain the battery.

    Also I'd honestly fuse it because any shorts or faults in the mirror may shred the BCM circuit and kill the module.

    All good - Tested it multiple times to make sure it goes off. If you want you can run it off the DOC but I am very confident in the feeds i have picked. If you use any of teh other dome light wires these will stuff your Can bus and cause issues!

    Very nice

    Although, Im assuming that learning in your remotes will only be possible if you have a fixed code system. If its rolling code, its unlikely it will work.

    Homelink in the US works with rolling code. It comes down to the frequencies mainly

    It has an LDR (light dependent resistor) in the back (windscreen side) to detect if it is night and then an LDR in the front (car interior facing) to detect light shining at the mirror from behind. When the light reaches a level that is above the tolerances the mirror will automatically dim (go green) to minimize the impact on your eyes.

    They are hugely popular in the US, i think the caprice gets it here, also territory Ghias get it.

    Could one of these be fitted to a redline? With all the lane departure stuff, it looks like it completely surrounds where the mirror is?

    So I bought myself an auto dimming mirror from a WN Caprice. Does anyone know if the plug is hanging there in a VF2 SSV Redline, so it can just be a plug and play? Anyone got a crashed VF2 SSV Redline that could check? My car is yet to be built so I cant check

    Just wondering would any Homelink mirror fit in a VF or do you have to get a specific one? There’s plenty for sale on eBay but I don’t know which one will fit in my VF.

    There are 3 wires to join up. Power and reverse lamp. The Calais/Caprice mirror is the same as the Colorado mirror in the LTZ model. To buy retail it would cost around $195

    From when I did mine...

    I only wanted the dimming so wasn't concerned about remotes or non-dimming in reverse.
