i have a very outdated navigation unit in my vehicle and after buying a new gps unit i found out there is no easy way to install a new gps unit (its got special sensors and yada yada)
so i figured out i can hook up my aux on the existing unit that will come out to have RCA connections (red white yellow)
my question is how can i hook up my phone to this rca connection so i can use the nav on my phone/listen to music ect.
my phone i have now is the LG Intuition. I Dont even know if this phone has any video out option- if not i will be getting the galaxy note 2
i imagine a few possibilities
CAR UNIT- RCA- RCA to microUSB (some form of adapter) - to phone
CAR UNIT- RCA- RCA to 3.5mm (some form of adapter) - to phone (i saw that on youtube)
CAR UNIT- RCA- ???????????????- to phone
please enlighten me as to what adapters/cables i would need and if it were to be possible
also for refference my vehicle is a 2005 Volkswagen Touareg with the nav unit : VOLKSWAGEN RNS2
If you have 3xRCA in RNS2 it's good, but RCA is a composite video signal(Analog video), new smartphones have hdmi(Digital Video).If you need video from smartphone in navi you need converter hdmi to analog rca.
I could be wrong
Just installed a Joying:
. SKU: JY-UL124 . Quad Core Android 5.1.1 Lollipop OS Capacitive 7" High Definition for Universal Double Din . CPU: RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600. RAM：DDR3 1G, 16 GB memory
To my 2014 Australian Hyundai Elantra.
I waited to get the latest HU from Joying that has an unrated mother board and USB/ Comms board. With Lollipop 5.1.1. the unit performs very well with none of the problem previously mentioned on these pages. The internal and external mics are clear and the Bluetooth systems are perfect. Unit has been rooted and I don't seem to need for apps so I won't changed the software.
The dimming for the button and the screen to follow the vehicles rheostat was fixed by making a circuit to invert and amplify the rheostat output to the HU ill line. Work's well, Kudos to the guys at the Subaru forums.
I had one bug fixed by Joying when the GPS nav was muted whenever I plugged in the DVR front camera. Joying quickly sent me a link to re flash my firmware and the problem was fixed. I have them currently looking into a bug when I view the DVR input shown on the HU I get lots of flashing to the screen in all pixel settings. I have been told this will be fixed in the next firmware update soon.
One problem that I can't solve is when I try to use my vehicles Multimedia Jack located in my center console. There is a Aux and USB jack there. All wiring from console to HU is complete. If I connect a USB stick to the Jack in the console then then HU struggles to connect and gives up. If I interrupt the USB plug and socket behind the HU then I am able to use the USB correctly. Looking at the car wiring diagrams there is a amplifier cct behind the Multimedia Jack supposedly to amp up the USB to HU. Doesn't seem to work?
Any ideas appreciated.

If anyone has any ideas on
i have nothing to add, other than interested to see what the result is. Are you saying that your car comes with a built in hub in the console, and you are trying to make that USB port in the console work to the Joying head unit? my vehicle is similar, and I would like that to work as well
Update
Yes I have a console hub I guess.
The book calls it a multimedia center. Just an Aux port and a USB port or Jack in the tidy bin in the center console. If I by pass the Jacks and directly put the USB stick into the USB tail from the radio then it works fine. When I plug into the console port it tries to read it and fails. The HU then reports a read fail, have tried other known working USB sticks.
I have inspected behind the console jacks and found a cct board attached to the Jacks and then to the car wiring. From looking at the diagrams of the car previous to mine I see a cct board containing what looks like an amplifier. Tracing the car wiring to the radio input connectors seems to be OK and the wiring correct. Voltages at the radio connector are right in that there is 5v +ve, negative - earth and the center pins are data as they should be.
The console Jacks

The wiring for same (mine is same but more complex)

Really bugs me not to be able to access that USB input Jack esp as the radio is a great unit.
You need to post this question in the MTCD (Lollipop) hardware thread. This thread is for MTCB (KitKat) units. The hardware in the MTCD headunits are very different than the MTCB headunits.

Am I still in the wrong section?
Yes, the MTCD thread is for the headunits with 5.1.1. The hardware changes and software are different. Send one of the admin a message and tell the why you need to get the permissions to post. I had to do that some time ago. Just make sure you follow the rules when post or you can have you account suspended or whatever the moderators deem necessary.

Ok thanks for that. I don't seem to be able to find how to "Send one of the admin a message" Can you help?
Just for info, there are both MTCB/C and MTCD/E Lollipop units.
Hello
Today I installed my back up camera to my PX5 6.0 Android unit with the Rockford fosgate system. The Android unit says it's MTCE_HA_V2.85_1 and I wired the wires to my reverse light power and ground and plugged in the RCA cables but I didn't do anything with the wires attached to the RCAs. When I put my car in reverse the reverse mechanism triggers but instead of the video from the camera it's just a black screen and the parking lines. Any help would be greatly appreciated.
Check the power supply of the back up camera and the yellow RCA connector. Connect the RCA connector that labeled CAM VIN but not AUX VIN.
I have a Seicane headunit and it has inputs for CAN HI and CAN low. If I connect these straight to the Canbus could I pull the OBDII data from the car? or is a CANBUS decoder required? I don't need it for steering wheel controls or anything else. I would just like to see some OBDII data.
Head unit is a PX5 4gb+32gb
If you're talking about the 2 pins on the harness connector that goes to the car those 2 wires go to another smaller connector that plugs into the CANbus decoder. So yes you need a CANbus decoder but those ELM327 OBDII dongles are dirt cheap.
Hi All
I bought a Kunfine head Unit and a aftermarket reverse camera. I hooked up the reverse camera to the reverse light and ran the cable to my Kunfine android 10 head-unit. My Head-unit does not have a dedicated reverse camera Socket for my RCA cable coming from the reverse camera. So I plugged it in to the CCVB and i got an Image, but i have to select AUX on my head unit to see the image from my reverse camera. The unit also dont have a dedicated wire to fit to the reverse trigger wire. Can anyone tell me what i must do in order for the reverse image to come up on my android unit as soon as i put my car into reverse. There are no "back" or "reverse" wires on my head-unit canbus... Please help. I will really appreciate it.
Thanks

Is it an MTCB unit? What is the MCU version?

It's not an MTCB, try searching for your MCU version and posting in the Android Head Units forum.
