Just spent the afternoon freezing my nadgers off having a go at fitting my reverse camera / number plate light (suitable for BMWs!) to the FFRR. It doesn't fit.



The design of the number plate holder on the FFRR doesn't provide enough room for my camera and light to slot in. Also, the LED light gives a number plate light check warning on the dash, although it goes away if I reconnect the original bulb and have the LED one connected too.



The number plate light casing (also for the boot handle switch) is quite fragile. Broke a couple of parts whilst dismantling to see how it all works so take care. Removal is straightforward (though not mentioned at all in my version of RAVE), just undo the four torx screws and prise out. You can then remove the rubber boot to access the back of the bulb holders and the wiring connectors. Didn't find where the cable went to though.








I have had all the trim covers off the upper tailgate to have a look at cable runs. You will have a few broken clips, especially on the bottom trim once you get them off. Fortunately these are the replaceable type, like on door cards. Do the bottom first, then the top, then the sides. For cabling, the only tricky bit is getting through the rubber boot into the roof space. Seems better to use the one on the left (as you face the boot of the car) as there are less wires going in there. Other than that plenty of space for running wires along the back and sides.









Also need to find a suitable ignition live for the camera on the tailgate, would save running a power cable all the way back into the car. I guess the power to the rear wiper might do it, just not much slack up there.

So options are (for this fitting):

1. Cut a new rounded rectangular hole in the upper tailgate, make up a grommet and shroud
2. Dismantle reverse camera casing to make it fit
3. Cut up one of the bulb holders to make it fit
4. Fit it inside?
5. Forget it and find an alternative

Quite tempted to try 1. .

Useful hack:

Take one of those tape adapters with a 3.5mm jack, they are only £1.50 on the bay, cut off the cable, stick it in your cassette slot, and the car thinks you have a cassette in so it works your audio etc. No need to run a normal cassette tape in there. Smile .

Nearly ready to do my installation.

PC will be running Xubuntu Linux 11.10 and uses openbm-gateway and XBMC as the front end. Managing sleep and hibernate has proven too complicated/messy so have opted for simplicity given it only takes about 30 seconds for the PC to be ready.

So PC is switched on using a switch which is hard-wired to the power button, then it runs a bash script to start up the ibus interface program (openbm-gateway) and XBMC which starts up playing a pre-defined music playlist. I have popped in an option when the ignition is turned off just to give me access to the PC in battery mode if I need it. There is also a program called xrandr which is used to turn off the PC screen whilst the other screens remain on, and this can also be used to overcome the brightness issues I am having with the main front screen. The script stays running all the time, constantly checking for the programs needed to run the system, starting them if they are not running, or shutting everything down when we go to battery power. I was able to achieve most of this on a Windows OS as well using vbscript and as XBMC is cross platform the only thing needed is the ibus communication program between ibus commands and xbmc (this is where linux wins! - had to get it in somewhere Wink)

For the geeky amongst you, here is the script:

#!/bin/bash

### powerwatch.sh
### created by Joe90
### for carpc
### run this script on start up of laptop
### will start all required programs
### shuts down laptop if ignition switched off
### should keep working after a sleep or hibernate too?

while :

do
   if on_ac_power; then
      sleep 2
      ### starts xbmc
      if [ -z  $(pgrep xbmc.bin) ]; then
      xbmc &
      fi
      ### starts openbm-gateway
      if [ -z  $(pgrep openbm-gateway) ]; then
      openbm-gateway &
      fi
      ### blanks laptop screen (its in the boot!)
      if [[ $(xrandr -q | grep "current 1024 x 600") ]]; then
      xrandr --output LVDS1 --off
                xrandr --output VGA1 --brightness 2.0
      fi
   else
      ### turn laptop screen on
                xrandr --output LVDS1 --auto
                ### dialog popup to allow user to cancel shutdown
      ### for whatever reason. Defaults to YES after timeout!
      zenity --question --text='Do you want to Shutdown (Yes) \
      or continue working on battery power? (No)' --title='Shutdown ?' \
      --width=400 --height=100 --timeout=5
      if [ $? = 5 ]; then
      ### shuts down xbmc gracefully (?)
      wmctrl -c "XBMC Media Center"
      ### shuts down openbm-gateway
      killall openbm-gateway
      ### shuts down laptop, assumes script not run as root
      ### resolves ttyUSB0 assignment, only takes 30 seconds to boot
      echo "xxxx" | sudo -S shutdown -h now
      else
                xrandr --output LVDS1 --auto
      exit
      fi
   fi
done


Still got some interference on the radio due to the power brick for the laptop, hoping to sort this out with some ferrite cores, or may need to fit a ground loop somewhere.

Have decided to make up a block/spacer, and then to drill three small holes in the tailgate to take the reverse camera fixings and wiring. .

Solved dim screen by accessing secret bord monitor menu and whacking up the brightness.

Here's a screenshot of what's going on on screen

Correct daveo Smile I am not using carx.

Xubuntu 11.10 (an xfce variant of Ubuntu Linux for my OS), XBMC and a small program called openbm-gateway that connects to the ibus and sends commands to xbmc via the bord monitor buttons.

This will give me:

music, video, digital tv (and radio), reverse camera, pictures, weather. If am lucky, the guy who wrote openbm-gateway has also written plugins for xbmc that control the on-board radio and OBC and I may be able to use those also. The kit will run to all three screens in the car and sound out of car audio system.

also can use my android smartphone as a bluetooth remote control for the system and back seat passengers.

Working on the write up to go in the front part of the thread, but need to install the reverse camera first. .

Reverse Camera fitted and PC Power Button Fitted

Slow old progress doing the wiring but finished installing the reverse camera today.



Had to drill two small screw holes and two larger holes (to allow phono plugs through) to the underside edge of the upper tailgate, then ran the power and video wiring round to the top of the upper tailgate. I tried several times with various poky things to get through either of the two rubber gaiters between the tailgate and the roof, but failed, so use the existing hole in my headlining left by removing the wireless transmitter to run the cables. Might find a suitable box to hide the cable, but it's not too unsightly.

The camera fits in nicely between the licence plate lights and the reversing lights with the boot is closed, and is just about flush.

Plan is to access the live stream from the camera via XBMC using a tortuous xdotool command (converts virtual keystrokes to real ones), by capturing the going into reverse iBus message and running it. Something like this:

"80 0C BF 13 01 11 00 00 00 00 12 00 00 22" = xdotool key Escape Escape Escape Shift+v Return Shift+f Return Down Down Return

Alternatively I can feed it into my vacant AV socket, just means I would have to manually select this.

Also, having run the wiring down the side of the car I was able to fit the Power On Button for the car pc. This entalied drilling a hole into the coin tray to take the switch and then feeding the cables up to it from the footwell.





Have to buy another similar switch with a light in it, for turning on the 12v supply to the PC (this to avoid interference from car adapter and a useful shutdown alternative)

Now warming toes in front of fire, awaiting roast dinner Wink .

It's been too cold to do any more work "on the car" this week, got some soldering and wiring to do, suspect too much shivering wouldn't make for a good contact.

In the meantime I have fitted a 3.5mm jack input into the case of my netbook and soldered up the wires from the on/off switch to it. Makes it easy to plug a 3.5mm jack connected to the momentary switch up front.

Also been trying out a new skin on XBMC - SLik - much simpler and bigger selections.

Using a launcher plugin (Advanced Launcher) I can now run digital TV using mplayer instead of the built in live tv setup. Just easier to use, and can/may use the same method for the reverse camera .

Well I have choices but not really thought that far ahead (don't use SatNav much as I have a pigeon's brain Wink):

Google Maps on the Android phone (have to figure out how to get it on screen or just use it on phone)

Or

Just use the OEM SatNav - yet to see if it will "speak over" XBMC (I have yet to resolve a problem from when i moved to linux is that I cannot get back to the OEM screen once the carpc is running)

Or

Get GPS running on the carPC and use google maps I can use the phone as a gateway .

Wired up the power today with the illuminated toggle switch

Click image to enlarge


Note: power source to switch and ground from accessory is accessed from the live/ground wires in the boot. the ground for the illuminated switch is onto a screw under the passenger footwell closing panel. As a failsafe I have a 5amp fuse in line, which should blow before the radio (fuse number 8 ) does!

Switch in place


Switch on with light on


Just a few more tweaks to go and we are ready for final installation. .
