Mein Auto: 2008 BMW 750Li
2008 BMW 750Li E66 Add on HQ bluetooth audio streaming

My 6 CDs changer turns grey years ago, only single CD works, a couple month ago I come cross two close CD quality Bluetooth music receiver and try both on 2008 E66, the sound quality I must say very close to CD if you have proper front end device like smart phone or tablet support Bluetooth aptX or at least A2DP profile.

Most newer Samsung and Sony smartphone support BT aptX profile, they are the best sound quality, all Iphones don't support aptX BT, its A2DP is good but not good than aptX

One thing you may concern is that how about BT hand free phone goes to the car, I tested and found the result is perfect as smart phone can connect both car's BT and addon audio streaming device at the same time.

The set up is quite easy when you open your armrest console. after pairing each other and you should go Entertainment screen, choice AUX as input, adjust volume level as you like and you are done!

What is aptX?

Here are some photos for setup and devices connection

Side notes:
StarTech.com BT2A: $54.- best value, sound crispy but a bit less bass compare with B1.
Audioengine B1: $189.- best sound quality for desktop use,but also can be used in car, as tested this one has more sound balance and more warm

Both use 5V USB powered and size is 3"x 3" and low power like around 300mA.

Both use HiFi entry level DAC chips***65306;BT2A with Wolfson DAC chip, B1 with AKM AK4396A
