Install Hualingan on e39/e53 DIY

[fmugur]

Depending on your camera. They come with 4 or 3 wires (the ground is common). The HU needs +12 to the wire labeled "back" to switch the input to the camera. Do not use the video input for the backup camera, use the right RCA connector.
If the camera is not powered or there is no signal on that input you will get a message on the screen about that.
If you don't send +12v to the "back" wire your HU will not switch the input.

Thanks for responding.
I found out yesterday about 12V to the unit from carsolutionsdude forum...
What "right"RCA are you talking about - I dont think I have one...I have several inputs for RCA audio, one input that says "Video In Back" and thats the one I used for the camera.

Fmugur - right now I have my positive and negative connetect to my reverse light. I also need to bring 12v to the unit. Is it possible to take it from the reverse gear instead of going all the way back to the trunk?
If yes, do you remember which wire to use at the gear?

Thanks.

Ok, when I connected camera and a wire " back" from the unit to reverse lights I got nothing... When I connected camera and " back" wire to my old audio harness which had Positive and negative wire I got picture from the camera so I know it's working it's a constant power and I want it to work when I shift the car in reverse....looks like reverse wiring cannot switch the camera, not sure why.
Anyone knows what I can use to power the camera and back wire from the unit so it will work when i shift in reverse.

Philly, I don't understand what meant when you refer to the old radio connector.
All you need to get the camera working is power, and to have the camera powered only when you backup you need to connect it to the reverse lights. To do that there is no need to got to the bulb socket, you can do that on the trunk and tap into the wires from the gate harness. Hualingan system switches the input to the "back video" RCA (yellow rca with purple wire) when you put 12v to the wire labeled "back". So, if you use teh same power wire that you power the camera with to go to the front of the car where the Hualingan system is and connect it to the "back" labeled wire you should get it working.

Here is a reference to a oem camera retrofit diy that might help you.

There are a few types of backup cameras but there is one that you can find probably from your supplier specially designed for your X that has the power wire on the rca extension so you can plug the rca and to the backup camera and you only need to tap into the 12v revers power. The ground is from the HU/RCA.

Hi guys

I am brand new to the forum, very informative forum. I like it. I have also purchased the Hualingan for my E46 330i, and was wondering if anyone has any of these problems and if there is any suggestions or fix that people have come across.

1. The music player will start from the first folder.
Let’s say you have 10 folders with 20 mp3 files in each and you were listening to song 3 on folder 6 for example. If you change to radio or you switch off the ignition, when you go back to music player it would start on folder 1 song 1, then you will have to skip all folders to get to where you were. Another; if you are listening to folder 9 for an example and all the songs in that folder have all played. The hualingan will not go to folder 10 instead it will go to folder 1 song 1


2. Silence
If you are playing music player again and you receive a phone call, the radio would mute the music so you can use the phone via Bluetooth, but when you finish the voice conversation the player will start and you can see it counting on the screen but there will not be sound until you quit music player and go back in it, even if you press the mute button nothing happens, or you turn up the volume. Which this time you go to folder 1 song 1 again

3. The AF (RDS)
The AF button only works for the first time after i change the radio country until i switch off the car, when i later use the radio the AF button is now disabled, like greyed out. To get it to work again i have to reselect the country under setting and then re-tune all my favorite radio stations, well until i switch off again... and so on and so on

4. Phone book function
I have an Blackberry Bold 2, the address book function will just hang with an hourglass forever and i cannot use the phone-book function on the hualingan, i have tried also a Nokia n97 same story.

Firmware
I just think that most of the my problems are firmware related and can possibly be fixed via a firmware upgrade? is there one somewhere?

Please help anybody..

any update on the tv-in-motion head unit? these people are starting to really piss me off

Hey everybody so I've had the unit about 7 months now and everything was fine but today I hit a bump and the radio stopped playing. Everything else works fine its just the radio. I did a factory reset, took out the unit and clean the connectors but still. Any help would be appreciated
