Yup, I have been doing some reading on the BlueBus and it looks like the ideal solution for what I need and it appears my car has all the wiring pre-requisites for it. Others might want to swap their HUs out, but my experience with the Chinese-made ones was not at all positive. While installation was pretty straightforward, functionality, performance, support, integration and reliability were no where close to what was advertised.

The one question I do have re BlueBus is how do you take advantage of the other iBus features and tweaks it offers (like the one touch indicator for lane changes etc) if you do not have the fancier Nav radio in your car to display configuring those options via the BlueBus? The videos show an E39 with the Nav radio being used to setup various options via the BlueBus but, I have a basic Business CD system.

Another question I had was can it support more than one Bluetooth device (like a tablet and a smartphone) at the same time.

Thanks for your response.
