Universal Wireless Car Steering Wheel Remote Controller - ALLOMN Bluetooth Audio Volume Switch for DVD Player & GPS Navigation System - Perfect for Hands-Free Driving & Entertainment Control

This will be the most useful review of this universal steering wheel control you can find. Really these instructions will apply to any of these Chinese aftermarket SWCs that use the two wire analog output. Before I bought this SWC I read the reviews, searching to make sure that this could interface with a big name head unit (not just the cheap android head units out there that have built in SWC decoders). I saw the reviews stating it worked to a degree with the Axxess, and worked well with the PAC, interface adapters. I know the Axxess brand so I started trying to get the SWC to work with that. To sum that up — don’t even try. I returned the Axxess interface and bought the PAC. It took me about 20 minutes to figure out which wires to connect together and how to program it. There are no instructions anywhere that clearly tell you how to set this up. That is partly because this is an aftermarket SWC, not an OEM SWC built into your car. It is also partly, poor programming instructions for the PAC SWI-RC-1. See my attached pic showing how to connect the wires together. I decided to run both boxes off of my accessory signal power, since they are very low power devices. They also share the 2A fuse that came with the PAC. So far no issues running it like that. The wire connections in text format, from SWC to PAC: WHITE -> WHITE, GRAY -> WHITE/BLACK STRIPE. It’s that easy. To program the PAC for the SWC button assignment, you program the buttons in a specific order for the brand of head unit you have. See my second pic for some popular brand button assignment orders. You can program each button for a short, and long press. You hold the program button on the PAC for a couple seconds till the LED turns green. Then within 7 seconds being pressing buttons in the order listed for your brand radio. For a short press, hold the button till the LED on the PAC turns red. For a long press, keep holding till the LED flashes red/amber. It’s that easy. If only someone had bothered to write it down. Oh hey, I did. It’s your lucky day. Now for the SWC itself... it’s pretty nice. The casing quality is excellent. It has button repeat if you hold the buttons down (very important for volume, and probably a good reason not to long press assign the volume buttons). It makes up for having to surrender my volume knob to upgrade to this floating screen head unit. Overall good quality and works really well. The one downside is that there are basically no instructions for any of these devices, for this scenario. Hopefully I’ve solved that problem for others.pros and cons to really cover this one, as I wanted to love it, but ultimately decided on using another brand.the build quality is there, well shaped and painted steel for the steering wheel clamp, uses a decent size nut and bolt. All the buttons feel good, LED backlight behind them is strong too.The wiring for the remote reciever box is good thick wire, 18 gauge, much thicker than competitors.the bad.. this thing is only really laid out well for using on the right side, so if you are operating a manual shifter, its kinda pointless...which defeats the point of it, since you have to remove your hand off the steering wheel to shift, or vice versa.If you want to mount this on the left side of the steering wheel, it ends up looking stupid because the button icons are upside down, as is the lettering..You also cannot reverse the mounting orientation due to the "jellybean" shape and the recess on the back mount.I REALLY wanted to like this, its definitely a better product than some of the others, but its not built with the idea of left handed people, or anyone driving a manual..pictured is the unit I replaced it with, also an amazon universal remote, that works and looks a lot better on either side of the steering wheel.This is my 2nd one of these i've installed in a vehicle, I use them for aftermarket radios so not the intended application, they are meant for adding steering wheel controls to factory radios, and all I'm looking for is volume controls and next track. So I'm basing my review on the fact that I'm not using as intended, as well as product quality.Great Build Quality:This is the main thing I purchased a 2nd time for. I tried the Metra Access Universal RF steering wheel controls, which is exactly designed for my use case, but it had issues, the main one is the flimsy feel of the controller on the wheel, it goes on with a big rubber band, even with adhesive backing it had too much flex to not get frustrated using. The ALLOMN adapter has a metal bracket that screws on to the wheel, if it's not tight enough you can add some padding and screw it back on,. And then the controller slots on and off the bracket easily for changing the battery, it is just a great design and the main reason for the 5 stars.Programmability, this is where it doesn't shine as much, but again I'm not using as intended. Using the PAC SWI-RC-1 interface to pair this with an aftermarket radio, results vary, as both the ALLOMN and the PAC SWI use resistance based signals, and resistance can change with wire length and temperature, and it seems like the ALLOMN signals are very close together, so just a slight change in resistance will cause the button mapping to change. All I want is volume up/down and next track, that's it. if I have 3 buttons on the controller that do that in a somewhat normal fashion then I'm good. I mapped everything out before buttoning up, then when I tidied up the wires and put it all back in the dash the button mappings changed, but it's liveable.I've looked for better options, if PAC would make something like the Metra with a better controller I think it'd be great, as their programming options are much better than Metra's. But for right now I'll keep on with this and keep an eye out for something better that feels as solid. The market for these isn't that big, and I think getting smaller as most newer cars come with Steering wheel controls standard so not holding my breath.
