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.<p>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?<p>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...<p>thoughts? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

I'd like to know if they are separate as well. I was thinking more for if I get the reflash and then my radio ****s the bed if the radio fix will erase the ECU software.

Re: (Crashy)

The ECU upgrade only changes the ECU software. It dose not alter any other systems in the car. This is the way that BSR's ECU upgrades work. I cant say if it's the same with other ECU upgrades. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

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

I wonder what the "Bluetooth" update does (?) <p>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.<p><br>

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)<p>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)
