I just installed the brand-new 590LM onto the KTM GPS mount. The unit fit onto the KTM GPS mount perfectly. I wired it into the ACC2 connector under the power port (which you can fish out with your fingers). Everything works great. ACC2 is "switched", so the unit powers on when I turn the key, and goes into battery-mode when I turn off the key. I merely had to purchase some Male "AMP" connectors and a crimper (at Home Depot) for the GPS power cables, so they would plug into the KTM's connectors. Easy! A great GPS paired with a phenomenal, off-road superbike. Love my new ride! Let's go adventure touring!
