Hi all,
I've been following this forum for years while owning my E46 330XI and I'm glad to finally have joined. I just purchased an E92 335i coupe and its a beautiful machine. However, it came with basic sound system and coming from my Harmon Kardon sound system from my E46, I was disappointed. Anyone know if changing the sound system will void my warranty? I appreciate your responses
