I think people underestimate the quality of a digital bluetooth connection versus an analog 2.5'' jack. IMO, if you're experiencing bad quality over BT, the issue isn't "bluetooth", but the codec being used by the source.

If it's using a low-quality codec, you're going to get low-quality audio. However, the blutooth profile used for sending audio wirelessly is capable of sending mpeg formatted audio, which is the same as what you would hear directly out of your headphones.

The iSimple media gateway will use your steering wheel controls for anything that is plugged into the gateway that is digital (ipod connection, or bluetooth). I can't tell any quality difference between the bluetooth and using the aux cable except the aux cable has higher volume at a lower setting. I am using factory bose though so maybe it just cant replicate the distortion

I usually keep the volume on the ipad all the way to max minus 1 and listen to the radio at 15 on the radio. ive put the radio to the max of 30 and it still sounds great but its too loud unless you like that sort of thing.

BT compression is much higher than just pumping in amplified music through a AUX port. Hence how an AUX input can sound better than BT streaming.

It's true that BT has a max bandwidth of 768kb. Uncompressed CD-quality music is approx 1.4mb.

I still contend that the quality of the connection (and hardware) along with the codec used by the BT connection as a result of that hardware plays a large part in the quality of the sound.

I personally wish the BT standard would be updated so that it would allow a higher bandwidth to the point of actually being able to stream "uncompressed" CD quality music (since CD music is compressed anyway).

From what i understand Bluetooth has a transferable connection of up to 1.25MB per second.

The industry has eased up on more BT technology and hasn't come up with something new within the last 2 years. But the point here is unless you are a fanatical audio enthusiast you are not going to get concert quality sound out of a vehicle. at bit rate of 512 or more your going to have a high quality sound without noticing the difference IMO.

I'm not an audio savant like some of the dudes like Bigaudio are. The transfer limit I think has to do more with the individual BT protocol (a2dp) that is used for the wireless transfer, which is the one I quoted that's a little north of 720kbps. I dunno.

From there, you're limited by the codec which can be as low as 200kbps. Some apps and some adapters cannot stream at the highest native BT codec rate which is still kinda low.

Here's some info about it. I'm not sure how current it is. I'd personally really like to see the native mp3 BT codec actually be put into play. I think sound quality could improve quite a bit from it.

Most BT streaming is not even close to what the max throughput is. It's like SATA 6.0 MB Throughput for hard drives, you will never see that speed. Another example is MAX power for an amp, you just will not ever see that. Most streaming in today's cars is not using the newest tech even, so your compression is much higher than the numbers would suggest. Given that I have streamed BT audio through many different head units I can certainly hear the compression even with newer head units, and that's using factory speakers even.

Would love to see some pictures of this.
