Spin4Air is currently working on POWER ADJUSTABLE WINDSHIELD for the Slingshot. Since the new kit will involve tapping into the system power, we're looking for dealers to help install our customer's kits. Some customers don't wish to play with electricity. This includes all the 12 Volt DC crowd. The system is much easier to install than a common stereo, so the 12 Volt people would benefit. Looking forward to our release of the new kit coming soon!!
