BT45-ACU and HandsFreeLink
I can't seem to find a definitive answer to this question anywhere (including from the manufacturer directly), and am hoping that one of you can help out here.
I'm looking at getting a USA Spec BT45-ACU module solely for streaming music via my iPhone 6S; I do not intend to use this device for phone calls. My question is, can I still answer phone calls using the steering wheel controls on Acura's HandsFreeLink system while my phone is connected to and streaming music via the BT45-ACU? This is for an '07 TL-S.

I think technically you should be able to, but why? The USA Spec lets you answer calls with steering wheel controls by hitting the channel up to answer, and channel down to ignore

I don't want to install their microphone in my car, and would rather use Acura's built-in system for that. Another TL owner on Amazon already confirmed that it'll work the way I want it to on Amazon, so I'm all set.

The only caveat to this install is that sometimes streaming doesn't start up immediately, and I have to actually press play on my iPhone's music app to get started, and from there can use the car's controls, but that's a minor point.
If you go that route, I would definitely suggest turning off the voice prompts on the BT45 (it's in the instructions), as they get annoying quickly.
In case it helps, I edited somebody else's trunk shot to show exactly where the XM unit is in the TL-S:

For the most part, yes. I installed it in the trunk, connected directly to the XM unit, and am only using the bluetooth music streaming function of the BT45. My iPhone connects to Acura's HandsFreeLink for phone calls (using the steering wheel controls like normal), and music starts streaming immediately when I turn on the radio to the XM input.
