Given all the hassle involved I would definitely recommend taking the car to Halfords and getting them to install it . They will make sure the camera is connected to the correct supply and the cabling is invisible. They really are first rate at doing what is otherwise a very tricky job which in my experience a lot of garages get wrong.

B G Lister It's a bit late for me to reply to your post now - but I can assure your that the voice command system of the Lexus 400h DOES allow you control the aircon - no matter wehat Lexus say. You can increase or decrease temperature by voice command.

Mini 0801 cameras and their later models are made by various Chinese factories, The current model is the larger 0806 which is slightly larger than its predecessors and has far more ventilation holes in its case. That's because the earlier models used to overheat. The quality is variable. It apparently depends on which Chinese factory actually made the model you have bought - but if you get a good one it does work., the picture quality is good and the big bonus with the Mini range is that the cameras are so small you can hide them entirely behind the rear view mirror. The Mini cameras all slide into a stick-on windscreen mount which contains the GPS. Four Gold plated pins on the camera's mounting lug take power from four pins in the GPS mount. They need to make a good contact to ensure you get GPS readings on your camera. You can by-pass the GPS mount and connect the camera direct to the power supply - but bear in mind that the 0806 camera has the new micro USB socket and requires the smaller, thinner micro usb connector NOT the mini USB connector. (You can buy an adapter if you are stuck). If you connect to your camera - or your GPS camera mount - to the Lexus cigarette lighter socket you should be fine - but don't be tempted to try to wire the camera with a hardwire kit to the sunroof power in the headlining . This is because - even though your hardwire kit will come with a converter which brings the 12v current down to 5 volts (which is what the camera needs) - the voltage is NOT stable. If you put a meter on it you will see the current fluctuates widely from as low as 1.5 volts to 9 volts . THIS WILL BLOW YOUR CAMERA. Your camera needs a stable and rock steady 5 volts - so always take your power from the ciagrette lighter or from the auxiliary power outlet at the base of the centre console via the cigarette lighter plug which arrived with your camera . That will take the 12v current down to a clean and steady 5 volts. Most makes of dashcam are intolerant of incorrect voltage so it's absolutely essential you check and double check the voltage they are going to receive is correct BEFORE you connect them up.You will need a USB voltage meter with mini and micro inputs to check this voltage - you can't do it with a conventional tester with probes.
