my 2014 VW Passat has an auto dimming rearview mirror. Will I still need a constant 12V source or does a factory installed auto dimming mirror use a constant 12V?

Factory auto dim does not provide a constant 12vdc source. There is one available in the headliner if you have factory sunroof option installed.. Hope that helps.

You don't actually need a constant 12V. The Gentex memory is non-volatile, so it doesn't get wiped when the power is cut. A switched 12V (like you already have w/factory mirror) will work.

I hooked mine up according to the package instructions on a Mercedes ML 320 with auto headlights. No need to disconnect the auto-on feature. The only complaint I have is that they sometimes turn off in the summer if the AC triggers the radiator fan to run at high speed. They sense the voltage change when the fans first engage . I presume that the voltage regulator may be a bit slow in adjusting the alternator output. 99.9%of the time, they work perfectly.They dim as designed at night when the Auto-on Headlights operate.

This bulb is designed to not throw codes. I have a VW and there were no codes. You should be good

It will work as your primary. Your lights will still dim unless you have a second battery and aftermarket alt. I have a 370amp alt from Mechman Altenators. Another option is to leave your stock battery and put the 3400 in the back. Run a 1 or 0 gauge wire to the back from your stock battery. Run the same thickness ground from the 3400 to a solid ground.

You are correct. This dimmer needs 12V input and will output 12V. It only can work with low voltage lights.

The vehicle I installed then on (96 GMC k2500 suburban) didn't have factory heated side mirrors so the replacements I purchased only are power. There are versions of this type mirror that has power/heat and a marker light.

Hi,Thanks for the question if the vehicle already has an auto dimming mirror, orhas a harness that has power then this will work, you should test your vehicle to check before confirming the order.Thanksautopartsotys

I have two strips running off one dash light in my car which operates on a 12 volt battery(this isnt to say that the strips are getting all 12 volts). if i had my tools on me i would run out and open it up again to measure for you.

I am no expert but have replaced a few mirrors. The heated/turn signal one has a different plug than the regular one that is just power adjust. I made the mistake of getting a non heated mirror and had to cut out the car connector and "dummy down" the wiring and replace the connector. Best suggestion would be to pull your connector and see if it has wiring for more than just adjustments. If you have a volt meter, put on the turn signal and see of you get blinking power through one of the wires. Good luck.

If it isn't auto dimming then there probably isn't power at the mirror. It's no big deal though, just tuck your power wire under the headliner to the A pillar and down to the area below the dash on the driver's side. Next, it's just a matter of locating a power source that turns on and off with the ignition and tapping into it. Escort makes a hardwire kit that is plenty long enough and I believe has everything necessary to wire into the fuse box. It also has a mute button and indicator leds built in. It should fit if there is fairly decent space between your mirror and windshield.

Brightness of the LEDs is controlled by the voltage level and current available. First verify that you have the LEDs connected to 12v source. The LEDs should be able to operate with 14v maximum. Unless you are using a very small transformer or have a resistor in the circuit there should be enough current. If you connect the LEDs to a 9v battery they will operate but be pretty dim. They should be much brighter on 12v but these strips are no where near as bright as what come on new cars as daytime running lights or turn/brake signals. Theses strips have too few LEDs to compared to the kind on cars. I use them as accent and to augment my turn signals on my motorcycle.

I ordered the one with the sensor because I have that large black box with auto dimming mirror, 911, and Assist controls.It fits perfectly. I don't have auto dimming headlights.

I bought a Lutron DVLV-600P-WH 600-Watt Diva Magnetic Low-Voltage Single-Pole Dimmer from Amazon for mine because I have it installed in a Juno 4" low voltage recessed housing, and it works fine.

Yes this mirror will fit your vw passat, I recently bought one for my passat year 2001. It's the same mirror and looks great! Hope this helped :)

It's clear like regular Mirror. Look at the part number on your mirror that you are replacing and match off of that. Mine turned out to have dimmer options and there is a difference. Not much but it is noticeable.

You do not have to have a constant 12v supply. It can be wired to the "backup" light so it will power up the camera and trigger the rear view display when you put the vehicle into Reverse.

you will need a positive wire from the battery. You can also make this work on your head lights with a TPST switch and a SPST switch.
