Will an ECU upgrade cause problems with other hardware upgrades?

When I got my subwoofer and bluetooth kits installed, both had software updates loaded so the car knows they are there, and adds them to the sound menus, etc.

If I do an ECU upgrade, will it cancel out the subwoofer and bluetooth software or does it only change settings that apply to the engine?

Just don't want to have to go back to the dealer after the ECU upgrade to have the subwoofer and bluetooth software loaded back on, and then have that clear the program for the engine...

thoughts?

I wonder what the "Bluetooth" update does (?)

I put the Volvo kit in myself and it seems to do everything it's supposed to without any update. I don't recall the instructions saying anything about a flash.
