Bluetooth Song track info not displayed in Car Head unit[AVRCP][Nexus 5x][6.0.1]

Hi,

This is my experience with N5X while streaming music through bluetooth to my new Car (Ford Figo 2015 -India).

Play quality - Good so far :)
Connection Establishment - Good so far :)
Upload Contacts to Headunit - 100% works :)
Display song track info - Doesn't work :confused:

I have seen devices like LG G2 (5.0 android), Iphones (4,5s,6), Samsung Galaxy Young(cheapest samsung running Jelly bean) connect and stream music info while playing music.

However my older Nexus 4 and my new nexus 5x seems to be hitting roadblock.

Please correct me if i am wrong, but below are my points that could be the root cause of this issue

1. MP3 Players(AVRCP support)
I have tried almost all renowned Music players from Playstore. Tried all bluetooth assistance apps along with them still no luck.

2. Bluetooth Stack
N5x is not listed : http://ift.tt/1TRrOnm

AVRCP version is not up to date ?

3. Bluedroid(previously BlueZ)
Bluedroid is still in its infancy and bluetooth stack not being upgraded, hence?

Please share your experience with N5X on Song track Info, maybe we could collate all information in this thread.
