Hook your Defender up to your home wifi and up date and install any maps you want, then get the BRP-GO app on your phone and hook it up usb to your buggy. It will give you everything you need without mounting anything else.
Just picked this up Friday. My last machine (Honda Talon) was fun but this is a cadillac next to that. I'm looking forward to many years of comfort and fun.
The new rig is a 2026 HD11.
