Eräs vaihtoehto on myös puhelin (toki auton järjestelmän myös tuettava), jonka Bluetooth on varustettu A2DP (Advanced audio distribution) ominaisuuksin esim. Samsung SGH-i300 jo vuodelta 'miekka ja kivi' on tällainen.
Windows mobile alustalle (Smartphone, Pocket PC) tuki A2DP:lle lisätty vuonna 2005.

AKU 2.0 for Windows Mobile 5.0 (for both, Smartphone and Pocket PC), which is expected to be released early next year, will also includes support for the Bluetooth Advanced Audio Distribution Profile profile which is designed to transfer a stereo audio stream like music from the device to a headset or car radio.
As always, it's up to the ODMs and the carriers, which AKUs are implemented into their devices and AFAIK they can also select/deselect features; so let us hope the ODMs and carriers will not make the mistake and remove the new Bluetooth profiles
