HOW TO CONNECT eBay BACKUP CAMERA TO NAVI

[SlickGT1]

Yes you still need the relay. Even Navtool instructions suggest a relay to the reverse lights. I still play on connecting the mini relay to the PDC. My electrician friend is working out the details on the setup. He should have time for me in the coming weeks to get this done finally. I will document the ordeal when that happens.

Hi,
i did read your post (quoted) and also the next ones, and it seems the others also are in doubt of the schema. Could you please, if you don't mind, make the schema of connections using the bmw tv tuner and relay?
Best regards and thx for your post.

The Ebay seller had my trigger wire tagged with + plus so all this time i've been trying to get a + current going through it ..... until today, i've had enough so i stripped everything down again .... started from scratch.

Anyway, there are so many wiring diagrams going around, don't follow any of them.

Best is to understand what sort of Relay do you have and most importantly, the TV needs a Ground/Earth signal for it to switch over, over-ride everything, even when the TV screen is OFF.

You won't need a good +12, you don't need direct power source from the battery if you're using the standard TV.

Simple! In the case if a 3 pin Relay is use ....

*Reverse light positive (+) to Relay
*Reverse light (-) to Relay
*(If you use 4pins relay, the extra pin will also need to be connect to a neg)
*Relay to Trigger wire

So when you engage reverse, reverse light + will activate Relay, Relay Jump/Bridge Reverse light Neg to Trigger wire, TV screen change to receive Video input from Reverse Cam.

Reverse Cam can be wire to any good 12+ sources on the vehicle, pending on where you're mounting the cam.

Hi
Not sure what you're after. Different seller sell difference harness (to connect aftermarket Camera to your X5).
All you need to remember is that in order for the X5 standard Tv screen to switch to reverse mode, the TV tuner PIN 13 need to receives a Negative flow to trigger/activate it.
If you need further assistant, i could try to take some photo of my set-up.

Try to get one that can install at the number plate, its WAY easier to install than anywhere on trunk lid, the part that lift up.

So while waiting for the new 'bullet', which arrived today, I got into wire 7 PDC middle plug and mocked up all the wiring.
I found when all connected up the relay switch would not click over - it seemed like there wasnt enough power going through it to make it switch.
I'll grab a pic tonight and see what I can sort.

which relay are you using for the pin 7? regular automotive relay? it should be the low voltage/amperage relay from the radio shack (35mA triggering amperage) or another one with the 17 mA - the specs are inside the thread itself...

Pin 7 does NOT provide enough power to flip an automotive relay...

Sorry for the late reply, i attached pictures of the camera below. it fits in place in one of the lights ontop of the license plate. I wanna go ahead and install it but no idea on where to wire everything. I also have a 40A Bosch relay, would that work? and to power the navtool would I need 12v accessory or constant?

[TerminatorX5]

have you tried to fit this camera into the license plate light opening? does it fit OK?

[euge]

yup fits fine just need to remove the bulb
