Additionally, WHD14+ utilizes the OEM radio antenna cable & USB media port cable. Simply connect the antenna & USB cables to corresponding sockets. Making installation even easier, WHD14+ needs only the bracket(s) & mounting hardware used with the OEM head unit. The faceplate of WHD14+ maintains styling of the OEM head unit, without the need of ugly trim kits.

Handlebar Integration Module Ready

Keep your hands on the handlebars and eyes on the road. With a little help from a handlebar integration module, key functions of WHD14+ like volume level, track playback, & phone call operations can be performed with the OEM handlebar controls.

IPx5 Liquid Ingress Protection

Exceeding expectations, WHD14+ was subjected to testing above and beyond industry standards, proving its suitability for long-term use in harsh riding conditions. As a result, WHD14+ earned an Ingress Protection (IP) rating of IPx5, protecting itself from any weather condition you’ll ride in, even after a quick trip to the power wash. Important factors like optically bonded LCD screen, sonically welded ABS assemblies, and silicone gaskets are all factors in ensuring WHD14+ performs reliably for every ride…
