Review on 🚗 2021 Newest Car Stereo Android10 Double Din for Mazda 3 2004-2009 | Eonon Head Unit Car GPS Navigation with Carplay/Android Auto | Fast Boot-7 Inch-GA9451 by Bill Maki

Okay, I was a little skeptical at first as other buyers have had bad experiences. so here's mine. As advertised, Eonon said buy the radio and get 3 free gifts. I contacted Eonon on June 1st to make sure it would fit my 2009 Mazdaspeed 3 Grand Touring with Bose system. They replied on June 2nd and said yes. I bought it on June 2nd and it was delivered on June 4th. I asked for freebies and they gave me 3 different purchase codes. Only 1 purchase code (front camera) did not work. BUT, I bought it anyway because I needed it. I started the installation on Friday 5th June and everything worked great (except for the rear camera). The rear camera has the feedback line to the front, next to the RCA composite video jack (yellow), and the positive and negative terminals on the back. camera case. I tried connecting the positive pole to the reverse light trigger leaving the front trigger wire disconnected and it didn't work. I tried connecting the front trigger line to the radio's power supply and it still didn't work. Finally, I decided to connect the red trigger wire all the way to the back of the car's reverse light and connect the rear positive and negative terminals to the battery. still didn't work. I came to the conclusion that the rear camera just doesn't work. I agree with that though, as I used this rear camera as a dyno to test functionality. This free rear view camera does NOT have night vision, so reversing at night isn't possible (but it's free - so hey). Later I will buy a night vision camera. The front camera arrived on Sunday June 7th. The USB extension cable included with the Eonon radio is required to mount the front camera behind the rearview mirror. Otherwise the USB cable is not long enough. The front camera doesn't have close-up vision either, BUT it delivers a clear picture during the day and on well-lit streets at night. Overall I am satisfied with the facility. The steering wheel controls worked well, the stock LCD worked well with the radio, and the Bose system sounded better with the Eonon than the stock. And the last. Wiring harnesses, CANBUS and BOSE system wiring harnesses take up a lot of space on the back of the main unit. So you need to be a little creative to thread the wires into the back without disconnecting anything. Hope this review helps others!
