I have a 2004 BMW 325i. I'd like to upgrade the speakers and add an amp. I'd also was interested in adding tv's in the headrest. There is a sticker on the front windshield that has this long list of electrical changes and mod changes that will automatically void any warranty. Does anyone know anything about this or how to get around it? I have like a 100,000 mile warranty and only 26,000 miles on it.
