Plug-N-Play Soundstream Reserve Motorcycle Audio by Precision Power are upgrade head units for OEM Harley-Davidson radios. Apart from the regular AM/FM radio and Bluetooth connection for phone calls and music, these units allow you to do the things you want as you can do in your car using Apple CarPlay or Android Auto. By plugging in your phone using the USB outlet, for V-1 systems or wireless connecting for V-2 systems, you can get riding directions, send and receive messages and listen/browse music, all in a way that allows you to stay focused on the ride. You can even use Siri on your Apple phone or the Google Assistant on your Android phone to find fuel stops along your journey. You can see it all on your radio's touchscreen display, helping you know more about what's nearby. The apps themselves have been reimagined for easier viewing, so you can use them while your eyes and hands stay where they belong on the road. Head units feature 7" (17.8cm) capacitive High-Definition touchscreen with customizable wallpaper/background .jpg & .jpeg via USB, USB Smartphone charging while connected (5V/1.5A), Low-Pressure IPx5 Rated Water Protection, built-in Equalizer, MP3/WMA/AAC/FLAC audio playback via USB (64GB Max), 50w per channel, 2 Ohm stable 4-channel amplifier, and 4V RCA Pre-outs, UV protection and conformal coated circuits. Units are bolt-in using the stock mounting hardware.
