RCA AUX In

Post by nyc eng » Sat Oct 12, 2019 12:34 am

Alpine ilx 207 headunit
RR 1 controller
2012 fiat abarth

I’m having a hard time figuring out where the rca “aux in” plugs from the radio F1 T-harness. Are they just spares?


Thank you

They are there to retain the OEM aux. You may need to use a RCA to 3.5mm adapter, as the alpine's inputs may not be RCAs. In this radio, you would have to plug the RCAs into an AV input, as Alpine disables the aux from being used as a regular aux input when you're using a maestro.

Hi Dara! Thank you for the information, I crossed something up.

My Alpine head unit has 2-3.5mm inputs,
1 input = "aux input" & the Alpine instructions say: to "AUX output or of iDataLink module"
the other = "steering remote"

I take it the correct way to wire it up is..
- RCA Cables "Aux in" (on maestro instructions) from the FI harness to the Alpine "Aux Input"?
- Maestro RR Module "Audio Cable" (on maestro instructions) to the Alpine's "Steering Remote"?

Nothing goes into the steering remote input. The iDatalink audio cable goes to Aux. If there isn't another input other than the one Aux, then there is no place to put the Aux RCAs. It's a limitation of how the radio was made.
