Installing this with the supplied hardware didnt really work for me - I needed something without the gap. I used the cage, side supports but left out the supplied mounting bracket as it didnt line up with the holes in the car. This replaced an after market radio so I had the proper mounting bracket for my car anyway. You'll want to check out your electrics to confirm your stock radio harness provides the expected connections. For some reason my red cable (ignition) was a permanent power, with the previous radio shutting down on a timer. This resulted in the Atoto not powering off when you turn off the ignition, effectively being permanently powered on, even when switching off from the front panel. Checked the fusebox and patched the Acc from there to the radio harness instead. Problem solved - it shuts down when the ignition is turned off. Needed a Fakra adapter for the aerial of this car as well as connecting it up to the power antenna cable of the radio. Some Wago connectors used for this - previously I would have soldered the cables, but hey if it works, why not!The only other accessory I bought was the AC-HD03LR, a camera used for the simulated panoramic view. This gives an overhead view after calibration and works remarkably well for a single camera implementation. You run a trigger wire from the Reverse light positive back to the Atoto so it can show the overhead view when you start to reverse. However I found the +ve of the lamp was a pulsed signal, not a steady 12v. The symptoms of this is, the camera switches fine when key is in Acc but engine is not running. When Acc and engine on, reversing does not trigger the camera. To solve this, use a 12v rectifier filter. All is well after that! The review was meant to highlight the tweaks you may need depending on your model of vehicle. My experience was on a VAG. The radio this replaced was more simpler, but when it broke I thought a radio is a radio and swapped back the oem radio. It was terrible! This S8 MS is so much better and just takes the driving experience to a new level. Being android opens up possibilities for geo-fence home automation and so much more.Anyway it beats a two line LCD CD/mp3 radio for sure!
