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?

Re: Will an ECU upgrade cause problems with other hardware upgrades? (ukmatt)

the bluetooth update may just be hardware. I looked back on the work sheet from the dealer and it does not say anything about a software update (my bad)

The subwoofer did require a software update, and it is noted on the dealer work sheet. You notice this update as the subwoofer now appears on the sound menu, along with treble, bass, balance, etc (where it was not listed before)
