DIY: Joyeauto Wireless CarPlay for NTG4.5/4.7
I put mine between radio unit and glove box. Had to remove Glove box and there is empty space where I put unit...
Little problems for arrange cables, i used duck tape an small Plastic Nylon Cable Ties.

Been following this thread and found all the install info helpful, thanks.
For the life of me I still cannot get the HU to go back in. A lot of you are right about the space centre below the HU and the harness block does seem to push down into it with some force, however it’s really hard to get the HU to clear it afterwards as you can’t hold it down and push in at the same time.
Any other pointers for getting the HU back in including the route of your cables would be very much appreciated.
Im installing into a RHD A207
It can either add a battery pack or it can depend on the aux battery alone.
I'm completely fine to use a external thumbdrive for the recordings.

Problem was wired....it didn’t turn on!! But after a bit of a panic that I had done some damage, I took the battery off and reconnected back to OEM and all is ok....phew!
ill try again but loosen up the cables from on another, the original loom is doubling up on itself now with nowhere to go. Wonder if there is a way I could pull the slack on those back down into the gearbox tunnel area so to remove the slack that I’m sure the HU is crushing.

Today I finally had success.
My problem when I got it pushed back yesterday (and then it didnt work) is that with the connector block in that 'hole' it doubled back the oem loom which would usually stretch for a perfect fit over to plug into the back corner of the HU. So had to find somewhere to keep these cables both out of the way AND not under any stress - i am sure the pushing I did was what stopped it working.
Anyway...I loosened off the fibre optics but cutting away the tape securing them to the HU loom....I removed the felt insulation which was at the back to see what was behind. I think it is the heater unit but it did also reveal a triangular void in the middle and some space underneath the heater box. So, I plugged the JoyeAuto harness into the OEM loom, positioned in down below in the centre then twisted it anti clockwise which spiralled the OEM loom around it taking all the slack away from the HU cavity. Then replaced the felt insulation once I could see that the HU would clear everything.
I had to then plug the 48pin plug into the HU very difficultly with my hand in through the hole above, where the central vents would normally be....took a while with the hole being so small but managed to get it clipped in....then guess what....it pushed back without any resistance!! Phew!
My god....that was tough....but I would offer detailed guidance to anyone that attempts this installation and gets stuck like I did with putting the HU back, so please just ask.
After that rock solid. Seems a little snappier and iosmirror with youtube worked without issue.
Time will tell if it is more stable and reliable to automatically connect. Half the time I must reconnect the bluetooth from ios
Still amazes me how well the Joyeauto device works providing wireless carplay. So glad I didn't go with the aftermarket android screen




Has anybody that has downloaded it still have a copy? And if so, can you share it?
Thanks in advance!
