Wireless music stream in 997.2 - super easy way via bluetooth!
 

Hi Rennlisters,

I thought I'd share a super cheap and easy way I found to stream music wirelessly in my 997.2. I bought a $16 Nulaxy Bluetooth headset on Amazon, which connects to the USB and AUX jacks. Pairing the phone and the device is simply, though you do have to press the headset button each time you start the car to setup the connection. It's amazing this great little device can make the car feel that much more modern. Here's a short review I filmed:


Cheers,

But is the sound quality on par with the cable setup?

I'm curious to know what the audio quality of this device is like. It depends on the codecs it supports. According to the Amazon product page for the Nulaxy Bluetooth kit it supports SBC, MP3 & AAC.

First, some Bluetooth acronym 101:
- A2DP (Advanced Audio Distibution Profile) is the profile for audio streaming. A2DP in and of itself doesn't speficy the codec used to transfer the audio on it.
- AVRCP = Audio Video Remote Control Profile. This allows you to press FF/REW/etc on the audio streaming device and it will transmit these commands back to the player, ie, your cell phone. This is of limited to no use in the 997.2.
- SBC = Sub-band Coding. This is the default (and mandatory) audio codec specified by the Bluetooth SIG. When Bluetooth audio streaming first came out, everything used this codec. It has really lousy sound quality and it often speeds up/slows down the music you're listening to like a rubber band. You don't want this.
- MP3 / AAC: Two very popular audio codecs with much higher sound quality than SBC, but at the expense of a higher latency. With these codecs there could be noticeable delay between pushing "FF" on your phone and actually hearing the sound change.

IMHO, what you really want is to look for a Bluetooth streaming device that supports the aptX codec. This is a newer codec licensed by Qualcomm that has excellent sound quality *and* low latency.

The Nulaxy audio kit shown in this video doesn't specifically call out the aptX codec on its Amazon description so I'm not sure if it'd be my first choice. It might still be fine but there are other choices available at similar price points that offer aptX, such as this one:

I should probably follow up my last post by saying Apple smart devices (iPhone) DO NOT support aptX. They support AAC. So the bluetooth streamer shown by the OP is probably the way to go.

FYI, Samsung licenses aptX so Galaxy S/Galaxy Note users can support it.

I don't know much about audio, but it sounds fine to me. I can't notice a different between the audio with the Nulaxy vs. the AUX cord. I notice a few times the audio skipped after I set it up. I'm not sure if it was my cell phone's connection or the Nulaxy acting up. I tried it again today and didn't run into any issues. For $16, this works like a charm!

Brilliant!!!

I bought a $3 usb bluetooth aux adapter and it works perfectly

How does that device work when the phone is connected with bluetooth? Will it switch between the two?

Are you piping audio (MP3s) via bluetooth from your phone to PCM?

Yup

Dan, could you please provide more info on what you are using? Perhaps a link?

Thanks!

...and can you answer the first question as well, thanks.

Modern as in 2004? J/K

But yeah, these bluetooth to Aux in solutions have been around for more than 10 years.

In the "modern" age, you can control your phone via the car's interface wirelessly.

Is your device a single USB BT dongle or a USB done with a pigtail 3mm AUX audio cable?

It would be helpful if you could identify the BT/USB device and your car's PCM version.

An interesting BT/USB/AUX solution:
