I have a Nexus 4 and I am trying to get it to work with my car computer, and for most parts via Bluetooth it works, especially for audio. I cant get the text messaging part to work, and that has to do with MAP profile for bluetooth.

When I had a samsung SIII it worked, but for some reason, with this it doesnt seem to work.. I heard from someone that it may be an issue and you need to install a custom rom. Is that true? Is there any other way around this?


It was broken in 4.2 when Google rewrote the Bluetooth stack.


MAP was never implemented in AOSP, the SIII only had it from Samsung tweaks.
