Here's how to install your converted system:
This image shows the additional connections your head unit will now have after conversion, and the additional connections fitted to the CD player. This is a non-TV unit - the TV equipped units have identical connectivity but due to the different chassis some of the components and wiring are exposed on the back of the unit:
The CD player is connected to the main touchscreen head unit with the following connections marked above:
- The CD CONTROL from the CD player connects to the CD CONTROL on the head unit
You then need to identify the following parts that you have either ordered separately or received as part of a pre-built conversion - this is what you'll have if your car has the STANDARD AUDIO system:
If your car has the PREMIUM AUDIO system you'll have the following (an additional Digital to Analogue converter and the Odroid SPDIF audio output will be the opposite gender so that it can connect to this DAC):
The Odroid unit can be hidden under the passenger footwell and tucked away up on top of the ECU module (metal box attached under the glovebox). All cables can then run under the glovebox and enter the area at the rear of the head unit ready for connection.
The GPS module should be installed up on the dash in the corner of the window at the passenger side, the cable is easily fed down under the glovebox to the Odroid by temporarily removing the dash side trim panel revealed when the passenger door is opened. Don't be tempted to hide this away in the glovebox or behind the dash - it may appear to work initially but won't receive a strong enough signal to get a GPS lock.
The connection process then is as follows and it is important which USB ports you use:
- Plug the BLUETOOTH USB module and the WIFI USB module directly into the main ODROID USB ports
- Plug the USB GPS RECEIVER directly into one of the main ODROID USB ports
- Plug the USB HUB into the USB OTG CONNECTOR, and then this into the ODROID OTG USB port (the micro-usb socket)
- Plug 1 x USB EXTENSION cable into the USB HUB, and the other end to the TOUCHSCREEN connector on the head unit
- Plug 1 x USB EXTENSION cable into the USB HUB, and the other end to the ARDUINO connector on the head unit
- Plug the ODROID POWER cable into the ODROID power jack and the other end into one of the 5V POWER connectors on the head unit
- Plug the HDMI CABLE into the ODROID and the HDMI INPUT socket on the head unit
- If your car is fitted with STANDARD AUDIO:
- Plug one end of the PHONO TO PHONO cable into the ODROID SPDIF OUT socket, and the other end to the AUX AUDIO IN on the head unit - don't worry if the cable colour differs from the socket colour
- If your car is fitted with PREMIUM AUDIO:
- Plug the ODROID SPDIF OUT phono plug into the SPDIF input of the the DIGITAL-TO-ANALOGUE CONVERTER, and the Red/Black plugs of the TWIN PHONO TO TWIN PHONO cable into the L/R audio out on the DIGITAL-TO-ANALOGUE CONVERTER, and the other end of the Red/Black phono plugs into the AUX AUDIO IN on the CD player
- Connect the DAC POWER CABLE mini USB plug into the DIGITAL-TO-ANALOGUE CONVERTER and the other end into the remaining 5V POWER connector on the head unit
- Plug the UNLOCK WAKEUP CABLE into the UNLOCK WAKE UP connector on the head unit. The bare ends then need to be wired in parallel with the passenger footwell illumination lamp in order to receive a wakeup trigger when the car is unlocked. The Orange (Positive) wire connects to the BLACK/WHITE striped wire going to the lamp socket (+12v), the other wire is the Black (Ground). Test with a multimeter across the wires to test polarity if in doubt (when your meter reads +12v when the lamp is lit, then the RED probe is +12v and the BLACK is Ground. If your meter reads -12v then the opposite is true.) This step is optional but recommended.
Now power everything up. You need to perform the steering wheel calibration routine described on the Operation page in order to use the steering wheel controls to skip track on your media player (see the Super Advanced functions - configuration mode section).
