This may seem like a dumb question but I was just curious if the "Chirp" on the E46 Alarm sounds different then the "Chirp" on the E36 Alarm. The reason I ask this question is because I was at my BMW Dealer today and I heard someone lock a new 528 and instead of a Chirp is was more like a beep. Can anyone tell me what the E46's sounds like? I currently have a 328 (E36) and am expecting my new 328 (with alarm) soon...I am just hoping that the Chirp sounds the same because I love hearing that sound! Thanks in advance!
