octesoNew Bluetooth Car Adapter - FM Bluetooth Transmitter Car with PD 20W & QC3.0 Quick Charge, Hands-Free Calls, Hi-Fi Music, Siri/Google Assistant, RGB Backlit, Aux Out

This is my second one of this brand, liking it for the USB-C port to charge my iPhone 12. The Aux line in to the car stereo is a nice feature and gives more volume than just via Bluetooth. This resides in a 2008 GMC Sierra work truck. When using the Aux/3.5mm jack, I get a high pitched noise thru the speakers that rises and falls with the RPMs but I’m guessing that’s a poor ground or something in the truck. None of that noise comes thru on Bluetooth mode. Also it’s a little slower to connect to my phone than my first one. Overall, love these units.

Update:After I left my initial review below, company reached out to find out what the issue was, and replaced the product without hesitation. Turns out the unit I received was faulty from the factory. The replacement unit doesn't have any of the performance issues that the first one I received had. I would not hesitate to purchase this again. And, I'll definitely keep the octeso in mind if they make something else I am in need of, I was definitely impressed by how they stood behind their product.=======================================Everything except the QC3.0 works greatFrom a functionality point I rate this as 4/5 stars, very well designed and seems to be good quality. My overall rating is 3/5 stars because the reason I bought it was for the QC3.0, and this does not meet my needs, but maybe I just got one with a bad USB port.This bluetooth FM transmitter works and looks great...EXCEPT for the QC3.0 USB port. The port doesn't put out enough to quick charge or fast wireless charge my Note10+. Bluetooth connection and sound quality are great as is the broadcast FM signal. The only other weak point is the volume control, as anything other than max volume is essentially pointless, however there isn't any distortion from having to use at max volume.

The enclosed instructions are great and it was so easy to set up and use! I really like it. However, with the volume on my phone at max, and the volume on this unit at max, I can barely hear the music. So, I have to turn the volume up on the factory stereo so much that if I switch to any other input source without remembering to turn down the volume then it is so loud that I risk blowing the speakers. This unit should transmit with more volume.

My sound is very fuzzy, and I’m wondering if changing the FM channel might fix the problem. I can’t figure out how to change it on the transmitter though. I held down the color changing button but that didn’t change the channel when I turned the knob, it just changed the volume. If someone could reach out to me I would appreciate it, I don’t want to have to buy another one. I’ve had this item for months with no issue.

Only problem I have is it doesn't auto connect, I have to do so every time. I'm still unsure how much power it draws if I just leave it in and don't turn it off which is much more convenient -- still it works as described!

I am so glad this works so well! I only use the Bluetooth and it is perfect for me and my old car! It is so quick and easy to set up and I am so glad to not have to listen to the radio.

I like that this has both USB A and C connections. I am. not sure if it can be changed yet it appears only one station can be deleted. The Bluetooth synced up nice though. So far no complaints although I know in certain places the programmer station will pick up the signal of an existing station on that preset. I didn't see a volume option. All in all, not sure how I feel about this. It replaced my old FM transmitter due to the phone using USB C. I enjoyed my last one as it has a small screen and more easy-to-navigate buttons.

Had some big tuners thinking bigger was better. This is small, stylish and works great
