Boom! Box Upgrade Paths for Every Ultra Trim

The 2015 Ultra lineup covers eight trims, from the Ultra Classic up through the Ultra Limited, and every one left the factory with Boom! Box 4.3 or 6.5GT — never the CarPlay-native GTS unit. Choose your trim to find the right upgrade.

About 2015 Harley-Davidson Ultra Models

All eight 2015 Ultra trims — Ultra Classic, Ultra Limited, Ultra Limited Low, and the Tri Glide Ultra Classic among them — share the same Boom! Box 4.3/6.5GT setup. To add Apple CarPlay or Android Auto, swap in a 2019-2023 Boom! Box GTS unit with a HogPlay GTS Bypass, or install one of the aftermarket radios sized for these dash openings.

Either route pairs with a HogPlay Media Box for wireless streaming and a USB Piglet for Mirror Link and AirPlay. There's no headset bypass for these years — the factory screen isn't gated behind one, so the upgrade comes entirely from the head unit swap or aftermarket radio.
