If nothing changed, I know your setup from years ago but since then, the technologies advanced so much that there are lots and lots of options available.

It really depends on what you want to achieve and the spec of your hardware/devices such as A2DP, etc.

If your OEM audio head unit still works and want to control the bluetooth device through the OEM unit, then the products from GROM will work as long as your device supports the required hardware spec.
Most of modern smartphone, devices, etc will work.

You will need to visit the GROM Audio site and check which product suits you best.
2 producrs.
USB3 - with optional bluetooth dongle.
BT3 - as the name suggests, built-in bletooth.

The bluetooth spec has been advancing over the time so obviously, having built-in bluetooth product has both the pros and cons from the hardware spec point of view.


I use USA Spec PA11-HON with external bluetooth receiver connected to the AUX port because I wanted to use the aptX feature.

As it is connected to the AUX port, I can’t control the target device through the OEM audio head unit - unlike the Apple device connected to the PA11-HON through I/F cable.
However, for my purpose, that is fine and personally, I won't use hands-free communication method without the advanced driving assistance feature

PA11-HON is no longer available, by the way.


If you want to leave the OEM system including the AMP and speakers as they are or if the OEM head unit no longer works, there are so many aftermarket options available including the ones designed for marine, etc usage.
There are several examples on NSX Prime.
