WTF is up with my Radio

[sixspence]

Right...

I have physical AUX input (hole) inside the center console under my armrest. It was a working function in the display with my old head unit before it quit working.
The new (used) head unit that I installed does not show AUX in the display as an option as I cycle through the Sources.

So I guess basically my question is are all HU650s the same and the AUX can be enabled and disabled OR do some HU650s have AUX and others don't.

That guy has a similar but not same problem as me.
He can actually see AUX on his display. I can not. I'm wondering if there is a way to enable the AUX.

I'm not sure if this means there is a high performance unit?

I think you'll have to go this route 2 videos - although the link below said this did not work so had to use something else

Hi, you need Arduino controller (Uno, Nano, etc. )and few cables. The sequence is written here http://gizmosnack.blogspot.fi/2015/11/a ... radio.html

From everything I've seen I still can't figure out if that is built in and displays after you have something hooked up to it OR it's a different unit altogether?

Will catch up with you later. Perhaps someone else will chime in tomorrow.

OK, one last interesting for now. Different part numbers so going to assume two different units with the same model number.

Exchange hu-650
AUX CH 644752- EXCH FOR 31260000, 31260310 (36002273) (8103771)
W/O AUX CH 502868-626605 FOR 31260304, 31260267 (36002272) (8103770)

I think you nailed it.
Oddly, the unit with the AUX channel is cheaper.
