Here's what I use for my iPhone 3G:
I have 3 basic cases:
Element Case
Contour Showcase
Agent 18 ClearShield + Marware CEO Premiere
Power Support Crystal Film screen protector
V-Moda Vibe II headphone
Motorola S9 Stereo Bluetooth headphone
2009 Acura TSX w/Technology package
- Built-in USB port for charging and playing your iPphone straight to the stereo
- Stereo Bluetooth Support for playing music wirelessly from your iPhone
- Handsfree calling
I also have a Toyota RAV4 and thinking of getting a relatively cheap Bluetooth head unit.
