Auto Volume makes adjustments according to speed and road noise. For the utmost clarity and accuracy, team this unit with one of the high performance PDX amplifiers.

Enjoy Superb IMPRINT Sound
You can connect the CDA-137BTi to the PXA-H100 IMPRINT Sound Processor to automatically fine-tune the sound for much higher clarity and imaging, or go pro with the PXA-H800 that gives you hundreds of tuning options.

High Quality Digital AM/FM Tuner
Alpine’s high performance digital AM/FM tuner finds and locks onto stations with extreme precision and virtually eliminates interference from multipath and adjacent channels.

Made for iPhone and iPod / Works with Nokia
This versatile head unit is fully compatible with both iPhone and Nokia (Symbian™) phones. You can enjoy the music stored on your phone, with easy control of playback functions and fast song search. The Direct iPod Control mode lets you use the iPhone/iPod interface for direct operation and for viewing information in your desired language.

MediaXpander Restores the Original Sound
iPod and other MP3 players sound good, but not as good as the original because the data is compressed. To achieve playback that’s closer to the pristine sound, Alpine developed MediaXpander. It enhances the frequency ranges where the sound is compressed, restoring the original vibrancy.

Built-in Bluetooth Plus
In addition to hands-free mobile phone operation, Bluetooth Plus gives you many other convenient functions, such as new telephone functions, improved phonebook functionality, text message alert and advanced media control. See the explanation below for additional information.
