I'm getting ready to attempt this. The desired end result is an Android head unit with a backup camera while retaining the OEM inputs, so I'm looking at:
Head unit:
Joying JY-TL123
(going with this one because of the CD/DVD drive...yeah, I'm old)
Harness to retain OEM USB port:
Axxess AX-TOYUSB
Harness to retain OEM AUX port:
Axxess AX-TOY28SWC
Antenna adapter:
Metra 40-LX11
OBD2 splitter so the HU and ScanGauge can be connected at the same time:
Obd2 Splitter Extension Cable Male to Dual Female Y
(this is the third car I've had my ScanGauge in and I'm used to it being there...don't want to get rid of it)
OBD2 to HU via USB:
ScanTool 425801 OBDLink SX USB
(I always go with a wired option over wireless when viable, so for me this is preferable over bluetooth)
Backup camera:
Esky EC170-06
After reading many many posts I'm pretty sure this is all of the correct stuff, but I just want to make sure before ordering all of it...if any of this is wrong or not needed please let me know!
If things work out in the usual way I'll get 1/3 to 1/2 way through then say "ugh fuck this" and wind up taking it somewhere to be finished
