This is the NBT Head Unit referenced earlier used on eBay for $300.

Looks like it was manufactured in 2012. It needs to be 07/2013 manufacture or later to be sure the SiriusXM channel art mod is on it?

UPDATE: See comments below showing date of manufacture/release.

Also its a Karman Hardon. I don't think I have the optional Karman Hardon audio system. Is the standard audio system a Karman Hardon in the 2013 535i?

UPDATE: The standard NBT HU is manufactured by HARMAN. Sorry for the confusion

Wonder if you could post a picture like this of your 2014 NBT (without the RSE)?

Does the NBT include the Audio Amplifier too? Where is the audio amp in the 535i?

How much you want for yours (without the RSE)?

Thanks!
