This was a very good upgrade. It was installed in my 2013 MX5. As you can see this is a 13-year-old car. The Boss radio was removed and I replace it with a Pioneer with a 7 inch screen. Therefore my connection of this device was done directly into the Pioneer radio. Not through the car. I read a lot of the comments of people before me about how they installed it. Their advice helped a lot with the installation. We learn from others. Therefore I took their advice, #1 uninstall my cellular connection in the radio system. #2 uninstalled the radio connection in my cell phone. Started all new connection. Once the item was plugged into the usb of the car. I asked the radio to find it, and it did (first try). Then I asked my pixel 8 cell to find the Bluetooth Android auto transmitter.But because my car is 13 years old. I thought that this would not work. And I was right. The car was too old. Therefore as you see in the picture. I then plugged the unit directly into the Pioneer radio unit which was more recent. Into the same USB port that I used to plug my cell phone in when using Android auto. It connected perfectly. Note, this will take about a minute or less. Take note that you will have time to start your car, put your seat belt on, and put the car and drive. All this before the cell phone will connect to the screen with Android auto. Again it's a Bluetooth connection. I found no lag whatsoever when talking to somebody, or changing an app on my screen. It worked perfectly. I placed it behind the glove box, under the dash. It's out of sight, and it works perfectly.When connected one time. It turned off my phone completely. And then my phone rebooted up again. But this was not caused by the Android auto Bluetooth transmitter. I have had this difficulty with Android auto on my phone just recently. It started since the last update from Google for Android auto. So I believe the problem is either with my pixel 8 phone or Android auto. It has nothing to do with this new connection.I think it's very important to follow step one and two that I've laid out. The person that suggested to do this, I believed help me connect this very easily first time. Your phone has to be disconnected from your radio completely. And your radio has to be wiped clean of your cell phone connection. By doing this and starting all over from scratch. You get an immediate connection between the two. Your cell phone to the Bluetooth device that is plugged into your radio (or usb port in your car). Have patience. Remember often when you can't get the computer to work. The problem is between the screen and the chair. In this case, it's between the steering wheel and the seat.This is great. I can now get in my vehicle and drive with my cell phone in my pocket, not laying between the center console. Safety first. Here in the province of Quebec, Canada. You can receive a ticket for having your cell phone laying on a console. A cell phone has to be fixed to the vehicle. With stand or something. This is to stop people from picking up their phones at red lights and texting with them.Please note I only connected my cell phone this way too my radio with the Bluetooth device. I did not pair my wife's cell phone to this device. So she can still drive my car and have her phone connected to the radio (like before) to receive phone calls. Her phone recognizes the radio, and the radio recognizes her phone. They do not connect to the new Android auto Bluetooth device like mine. But she can't use Android auto. Either way she doesn't use Android auto much. Also she doesn't like driving my sports car.... she's happy, and so am I.
