1999 V70 Aux / Bluetooth input ideas?

[BEJinFbk]

I recently installed the 'Yatour' unit in my 2000 v70xc. Very straight forward and works great. It was about USD100 from a German ebay seller with the Bluetooth accessory included.

Did you have to download software to get it to work?

No.
The SC-901 is an old school HU made by Alpine. It's a standalone
audio unit with no communications to the rest of the car's network.

If you're using a tape deck adapter, you could probably build you up an adapter that plugs into your headphone port using the appropriate pinout that splits into two connectors: one that goes to the tape deck adapter, and one that goes to a mic.

I did something like this on my old Maxima, though it was possible to wire audio straight into the radio so I didn't need the tape deck adapter. Worked well. I think I used something that split a headset cable into three RCA cables so I didn't have a gigantic soldered assembly to fuss with - I only had a few joints to solder in the end. You'd have to be creative to hide the spliced-up wires if you're using a tape deck adapter.

Ah, found some pictures.

The connector on the left plugs into the phone and carries four terminals, from tip to base:
- Audio left +
- Audio right +
- Microphone +
- Ground
(NOTE: This was for an old Nokia. Apple swaps the mic+ and ground so that you need iPhone-specific headsets and earbuds, so check the pinout for your phone before embarking on your soldering iron journey).

There's a buttload of couplers on the mic, though you could probably do that with a few strategic solder joints. The L and R cables went to the stereo - in your case, they would go to the tape deck adapter.

The way the Maxima radio aux-input hack was configured, you needed a switch wired into it to "turn on" the aux input. The mic was just a tiny mic from Fry's made to plug into laptops, and I pressed it into a hole drilled into a blank-off panel on the dash where some option my car didn't have would have had a switch.

I attached a remote control that came with the Nokia so that I could answer the phone or change the audio track without needing to handle the phone itself. The headset cable came out through a hole drilled in the back of the little cubby with the open door seen on the right in this picture. My phone fit perfectly into the ashtray, and I could plug the headset cable into it there. When I wasn't using this setup, I could tuck the cable back into the cubby and close the door and it would be hidden.
