Summary: The Alpine INA-W900 is a solid choice for most users' in-car entertainment and navigation needs, but it will require a few upgrades to match our current favorite in functionality.
Pros: The Alpine INA-W900 features a supercrisp screen for video playback and source selection. Full-speed iPod integration for audio and video are rolled in without the need for additional accessories. The navigation system features responsive destination entry and an accurate external GPS antenna.
Cons: Interface resolution is inconsistent between the navigation and source selection modes. The unit doesn't feature Bluetooth hands-free calling or audio streaming.
