Excellent Pioneer controller, essential if you want to operate the modern 2-DIN car stereos from Pioneer. It has previous-next track with the sexy-left, folder navigation with up and down, the sound is controlled from the back. It needs a special mount on the steering wheel; personally, I find it convenient to use a hack with rubber bands to rest it from the back to the front of the steering wheel, somewhat sideways because the buttons need to have resistance to work, either from the back or the front... If you find a suitable position on the steering wheel, you're lucky. It's handy. Attention: It needs line of sight to work, it works well, but when the steering wheel is turned the other way, it doesn't work. The last point is a detail.

when it is on the steering wheel it doesn't work unless you hold it in your hand in front of the source, and this is the second one, the first one didn't work at all after two points

It is not Bluetooth as stated (of course, no change in the description all this time). Only IR... so it requires line of sight with the unit.

It's great and very old in an s2000 for 4 years... very convenient and holds well... and if you want, you can take it off and have it in your hand with scratches... or the passenger..
I'm deducting 2 stars because the rubber that held the base got cut and I had to put a tire wrap.. it's a shame, others mentioned it too.

I will come back after 8 months, the rubber bands that tie on the handlebar are cut for fun!
Really unacceptable!!! 3/12/2023
It must be placed in this position to work properly! The signal is sent from behind and below! Overall, it works fine!

Wrongly referred to as Bluetooth*. It only has two infrared LEDs: "Infrared Remote Control, Wavelength 940 nm ±50 nm, Output typ; 14 mw/sr per infrared LED (2LEDs used)". I wonder why Pioneer includes it for use on the steering wheel (which is far from the sound source). It only works within 15 centimeters from the unit (SPH-DA360DAB), and if placed anywhere else on the steering wheel, it stops working. Unfortunately, I hadn't read the reviews and comments here before ordering it. What a disappointment!

*The ridiculous thing from Pioneer's side is that they refer to it as "Remote Control with Bluetooth Operation," but it actually means that it can answer or end a phone call (which is usually connected via Bluetooth). The communication of the remote control is in no way done through Bluetooth.

Indeed, you don't want to have fingers on the bottom part where the company logo is because you cut off the logo and it doesn't work. It works perfectly for me, I have it on the top part of the steering wheel so that the bottom part can catch the signal.

Combined with the Pioneer DMH-A340DAB. Although it is not on the list of compatible devices, it works fine. In a straight position and approximately 45 degrees to the right/left, it catches the signal properly, so it does its job perfectly. You don't need to look at the screen to change the station/song/voice. I would like a button for start/stop of the song, but I can live without it. 4 stars because when I installed it, I tightened it too much and damaged the rubber bands that hold it, but I fixed it. It requires a little attention.
