Swap Nav system head unit for Business CD head unit?

[bryanus]

I have the 10 spkr HiFi Professional DSP (aka "Analog DSP") sound system with Navigation (pop-up) screen, which is largely useless and sort of annoying how it continually pops up with every song change (I have the ipod and BT integration with an Audiovox Mediabridge).

Can I change out my head unit with a Business CD unit? I believe this would effectively disable my nav screen from functioning at all and just stay closed all the time. Would the Business CD head unit use the same wiring/harnesses I currently have?

Did the Business CD come with Bluetooth telephony support built in? I'd like to keep that functionality, too.

Don't know if you need the display on the non nav head unit or not but if your just using your phone you could just unplug the screen, everything else should carry on working
There's a removable panel below the ac / above ashtray pop that off , there's 2 connectors for the nav just unplug

Thanks. But I do need some sort of a display to be able to identify the different sources, hence the idea of swapping in the Business CD with its single-line display. I guess it should work as that unit was configured with the 10-spky HiFi system on many cars, but the question is if all Business CD units are the same across the years for our cars? Or do I need to specifically look for a 2006+ if I want to retain BT telephony (mine's a 2006).
