Harman Kardon radio question

[Th3Nox]

I currently have a 2012 Premium 1 LaCrosse with the Harman Kardon speaker system. I am planning on upgrading to a UHQ radio from a 2013 LaCrosse for bluetooth music, so I was just wondering if I will still have the Harman Kardon equalizer or if that is something that goes with the silver box itself. Also, will me having the Harman Kardon system cause any issues by going to the new radio from the 2013?

My guess is it will all be together as one unit, but I am not positive. I have a 2013 premium and the speakers say Harmon Kardon speakers. Have you considered just buying a Bluetooth adapter and plugging it into your input jack? Amazon sells them for around $20.

I have, but then the steering controls don't work, and I can't see any info about the music that is playing. Also when using the other sources it won't let me use the HK surround equalizer
