I have a few questions and need my peers here for suggestion.
I just purchased a 2004 BMW 330i ZHP for the performance, but just hated the audio system. It doesn't have enough highs and muffled lows. The HU doesn't do enough for me; i.e. doesn't play anything but CDs/FM/AM. Here are my options...
1. Add an IPOD connection so I can play mp3s, but shows no ID3 tags
$ 300 for installation and cable, $249 for mini ipod
2. Add an auxiliary input, for any external devices
$210 for 2 hrs labor, $39.95 for cable
3. Replace the HU. My thought here is I'll probably get better sound quality and additional feature. Some even comes with an audio input on the front for external devices. Electronic Warranty on the BMW is voided!!!
Anybody have any suggestions? I'm willing to shell out $2500 for an after market audio upgrade, but just afraid of loosing my BMW's Eletrical warrantly; that includes audio system, power windows, headlights and anything that's electrical on the BMW.
