Not sure how it attaches cuz I didn’t use it. I used the dbl face tape to attach to my dash. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Can't imagine an easier way to add bluetooth to a Gen 2 Prius *by on Reviewed in the United States March 2, 2020* I installed this in a 2007 Prius. I can't imagine an easier way to add Bluetooth to this car. The 12v power outlet and the aux plug are located adjacent to each other inside the center console. All that's needed is to plug this in, mount the microphone alongside the console using the supplied adhesive, and pair with your phone. I think it took me less than 15 minutes with no tools needed. The mic location down on the console isn't ideal, but it works just fine. It's much easier to mount it there than run wires up through the dash. The sound playback quality is excellent, thanks to the ground loop isolator. The only thing it doesn't do that the factory bluetooth does in my other car does is restart the stream when you restart the car. That's a minor vexation. It does turn off the stream when the car is switched off, which it the more important feature. I'm very happy with this purchase and wish I would have bought it years ago. ### ⭐⭐⭐⭐⭐ Works great in my 2015 Hyundai Elantra *by on Reviewed in the United States April 19, 2023* I will start by saying I have a XM radio but no Bluetooth (kinda shocked to be honest). I drive quite a bit but have never really liked having to hold my phone while driving. This device solved a few problems at the same time. Easily plugs into the aux jack I have in my dashboard. You will need to also have a USB power source to plug into (mine just happen to be located right next to each other). Once you have powered up, you can connect your phone to the newly created Bluetooth connect point and start using the phone hands-free. Now I can still have my music playing while being able to answer calls. Audio comes through the cars speaker system. Easy setup, easy connection, hands-free use...it's all there for me now. ### ⭐⭐⭐⭐ Cheap, simple, effective way getting a good Bluetooth to any radio with a 3.5 mm AUX jack. *by on Reviewed in the United States June 3, 2025* Works really well!Powers up quickly (no delay), connects quickly to iPhone, can be easily turned off (in case you do not want to be connected), controls are easy/simply.Sound quality - both music and phone calls - totally adequate for such a simple device. Note; in most cases you likely will need the Ground Loop Audio Isolator to remove any background hum. Included.Ding one star off as the unit sometimes (maybe once a month0 decides not to connect to the iPhone. It is of course always when I need it to be connected the most. Reconnect is easy, but should not be tried while driving. Hence the loss of one star. Oh, maybe also because of the direction of the buttons. Up/down should be volume, left/right tracks.After testing for a few days, pleased with how it worked, I decided to install the unit permanently. So in my case I removed a number of interior panels to route wiring, pull power from behind the dash, and to get everything is hidden away, part from the round control pad. ## Frequently Bought Together - Besign Bluetooth 5.3 Car Kit for Handsfree Talking and Music Streaming, Wireless Audio Receiver Ground Loop Noise Isolator for Car with 3.5mm AUX Input Port - Besign BK06 Bluetooth 5.0 in Car Speakerphone with Visor Clip, Wireless Car Kit for Handsfree Talking, Motion Auto On, Siri Google Assistant Support, Dual 2W Speakers - LISEN Retractable Car Charger, 69W USB C Car Accessories Adapter for iPhone 16 USB C Charger Fast Charging, Fathers Day for Gifts, Travel Essentials Gifts for Women Men, for iPhone 16 15 14 13 12 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/46579713-bk03-bluetooth-car-receiver](https://www.desertcart.be/products/46579713-bk03-bluetooth-car-receiver) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-21*
