Para saan ba yun USB port? For iPod or USB stick use? If iPod, you can always use Alpine's KCE-422 iPod cable... propriety, sad, but at least kaya ng 9887 iPod controls

How far are you planning on your sound setup? If you plan on building gradually. Splurging on a 9887 would be better in the long run rather than selling your existing headunit. But if you plan on a relatively simple setup (in other words: walang sali-sali sa competition), a Pioneer 6350 suffices.

As an alternative.. You might want to look at the Alpine 9886's successor. Forgot ko na kung anong model number but it should have a USB port (9887's successor is the CDA-117 if I remember)
