NVX XUBT3 Bluetooth Control

The following review is for XUBT3, which is a part of the bundle you are viewing.

Links instantly and sounds like it is connected thru cables crystal clear very impressed range is impressive also by far best I've tried

Won’t last long on a Harley

The following review is for XUBT3, which is a part of the bundle you are viewing.

Purchased this for my Harley which is not equipped with a fairing or stereo system.
XUBT3 is mounted to a hard saddlebag and connected to an NVX VADM4 amp. Since my bike is an 03, it’s not an M8 engine with the counter balance, which lessens vibration. My XUBT3 has lasted about 1 year and now increases volume on its own, shuts off, on its own and sometimes will not even power up.
My guess, it cannot handle vibration and it’s solder points must be failing.
As for me, I don’t think I’d recommend this for anyone with an HD motorcycle.

As clean as a cord long range

The following review is for XUBT3, which is a part of the bundle you are viewing.

Installed in Artic Cat sounds great links fast and has long range just wish it was a little smaller on back side bigger and cheaper than Wet Sounds but I can't tell any difference in sound quality or ease of use.

Perfect for my need

The following review is for XUBT3, which is a part of the bundle you are viewing.

This controller was very easy to install and works great. I needed something small and weather proof. This was mounted on a small space on the dashboard of a golf cart. The hole required is only 1" diameter and the full width about 1-3/4". I think it will be durable as it looks like quality powder coat. I prefer this knob unit to the dial on the control of NVX XUBT4, not only for the smaller size, but to the probable durability as compared to the plastic pressure buttons.

Blue tooth has excellent range and very clear sound.

NVX XUBT3 Universal Bluetooth Controller Knob

The following review is for XUBT3, which is a part of the bundle you are viewing.

This item was a lifesaver. Let the customer keep their oem radio and functions saving them a lot on a costly install.

Works great!

The following review is for XUBT3, which is a part of the bundle you are viewing.

Item works as described and has held up to rain and washing with a garden hose; both of which were issues for a couple higher priced/supposed "better" brand units I had prior to this one. Only thing I wish were slightly different would be for the track skip vs volume timing; I tend to skip tracks when trying to make a slight volume adjustment. Not a big issue, just something to get used to.

Works as advertised.

The following review is for XUBT3, which is a part of the bundle you are viewing.

Ok device for simple operation. Unfortunately the stereo separation is not that great for the connections,& Bluetooth. I ended up recycling my head unit in place of xubt3. Live, & learn.

works perfect for my car

The following review is for XUBT3, which is a part of the bundle you are viewing.

works well with using my phone/tablet as the head unit and this as the volume controller. This unit fits perfectly in the location of where the stock cigarette lighter was.

Works ok, but NO MIC!!!

The following review is for XUBT3, which is a part of the bundle you are viewing.

Beware - this unit streams music only. There is no mic so you cant make phone calls with it. Parts of the manual does not match the actual product. Its frustrating. Other than that, seems like it works ok.
