Suggestion
I have been very impressed with the voice quality on the built-in mic (wife has been able to hear me clearly fro the car) and the RF transmitter produces a reasonably clean signal.

Suggestion
Install is relatively easy, at least with the CDR-23 as you just have to pull the Head Unit out a bit to connect up the antenna / adapters, then just wire up the tranzit blue to the cell adapter, download an app to your phone to set the frequency and you are done...

You can tap into the cell phone adapter (left side of the center lower console) for switched power, and it uses an antenna adapter to plug into the back of the stereo.

I hate not being able to talk on the phone and use my commute time because I have to shift!
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey everyone. I have a 2003 c4s with navigation. Was wondering what the best option for Bluetooth would be.
would like to be able to accept phone calls and talk hands free. Would also like to stream music from my phone as well.
What are my options? Tried doing a google search and didn�t come up with much.
For $20 I got an rf cigarette lighter adapter. Has Bluetooth, charges phone, plays USB jump drive. Built in mic too. Called wife with it. She said it sounds just as good as the $2000 factory alpine in my Jeep.
I picked up one of these as well from Amazon for $20. The reviews were hit and miss, but it was cheap and had all the functions built in and figured it was worth a gamble. I have been very impressed with the voice quality on the built-in mic (wife has been able to hear me clearly fro the car) and the RF transmitter produces a reasonably clean signal. For $20 I've been very happy with it. Only drawback is no second 12V source for a radar detector on road trips.
I had wanted to do a dual-DIN conversion and ditch the PCM 1 system in my '99 C4, but the headache of dealing with factory AMP/DSP issues led to me going this route instead.
Overall, it's simple, effective, and cheap.
If you have an OEM radio, you might want to check with Becker autosound in NJ, they retrofit bluetooth to OEM units, they recently did it on an older TrafficPro radio for my 944. Just give them a call. My retrofit it music only, it does not include a mic for phone calls.

Best compromise between sound quality, ease of installation and cost I have found (not to mention keeping your existing setup assuming you are okay with the sound) is the iSimple Tranzit Blue HF (FM modulator). You can tap into the cell phone adapter (left side of the center lower console) for switched power, and it uses an antenna adapter to plug into the back of the stereo. I installed in my 986s (and bought another to install on my 996 that I got last October) and it sounds much better than the cig adapter fm modulators that connect over the air (tried a couple of those too and though okay the tranzit blue sounds much better).

Link to antenna adapters on amazon (these work for the head unit in both my 2003 986 and 2004 996 as they both have the same head unit - CDR23 - please confirm they work for your 2003 with nav as I think that's a different head unit but not sure).

Link to adapter to wire into the cell phone adapter on ebay. This is not required as you can tap directly into the wires (the hot wire is switched with the ignition) but I recommend this for ease of install so you don't have to tap in directly to the wire.

Good Luck!
My car has the same setup as MYoung73's. I don't try to use my phone while driving since I have a Cab. Streaming music works well. Need to replace the stock radio though as the CDR-23 has crap reception in my car.
