Take calls via car adapter

[bogdanb]

Hello!

I have an HTC G1. A few days ago I bought a car holder from Brodit for it, with a 3-in-1 adapter: http://mountonus.com/HTC-Dream/Brodi...868-20015.aspx

The adapter has a 3.5" plug for audio, one mini-USB for charging and one HTC Ext USB plug. I assume the latter has all the connections for the phone. (The producer says it's “for the original headset”.)

The thing is quite nice, I connect the mini-USB to a lighter socket for charging and the 3.5" plug to the sound system via one of those cassette adapters (my car doesn't have aux-in).

When plugged in, whatever makes a sound on the phone goes through to the car speakers, which is quite cool; no more risk of not hearing the phone ringing due to the music playing.

However, I can't figure out a good way of taking phone calls this way. I tried it once, the output sound goes correctly to the car's speakers, but the guy on the other phone can't hear me. I assume the phone's mic is disabled when a headset (or “carset”) is plugged in, and even if it weren't the car holder covers it.

I read some people successfully use a Bluetooth headset to take calls, but I really hate having things in my ear, and headphones in general.

Does anyone know a good way of connecting separate a microphone and headset via such an adapter? I would like to put a good directional microphone above the steering wheel, keep the audio output connected to the cassette adapter, and connect them at the same time. A proximity mic attached to my collar would work too, though I'm wary of adding more cables to the setup.

I was hoping there is some adapter that plugs into the Ext USB port and gives you separate mic in and audio out plugs that I can use at the same time. Worst-case scenario I might make one myself, provided somebody knows the wiring of the Ext-USB port.

Also, does anyone have any experience with a good directional microphone? I'm concerned that the audio from the car's speakers would drown my voice or create echoes for the calling party.

Nothing to add, but I'm very very very very interested in the outcome of this for my CarPC project - I've got (or at least will soon again) a mini-USB charging point wired up in my car for my phone / SatNav, but with my CarPC project I should be able to have everything plugged in and working at the same time - it would be great if plugging one cable in would then put all the sound through my car speakers, but for my situation a microphone is out of the question (i think at least).

I'm wondering if theres any way to keep the internal mic active when putting the phone in headset mode.

I emailed HTC (and T-Mobile) but no joy...

I have a Mercury with Ford Sync and it does the phone calls and music perfectly. The only problem I have is with the ringtone, I have one set and when I get a call through the car it rings with a generic ring tone not the one I have selected.

I had the same issue with my old LG Voyager. This fixed the problem:

This goes inline between your Android and your cassette adapter. It has a mic in the middle. I just clipped it to my seat belt.

NOTE: This was not the exact item that I previously had. Mine came from Verizon and they don't have it available anymore, but this item for the iPhone does the same thing.

Interesting thought, i completely agree with your perspective...
