This is the SWL of firmware version 4366 for all E-H revision RNS-510 units in U.S/Canada/Mexico.

This is the latest firmware for the E-H revision RNS-510 head units as of 6/22/14 and will add noticeable speed improvements to the unit.

Burn this .iso to a cd-r using IMGburn or any other program of your choosing.

Pop the disc in and hold eject+star+guide to reboot the unit and the disc should load. It may take a couple tries but it should boot the SWL shortly after.

Leave your car OFF/radio on, window down and check periodically after you acknowledge the install and let it do it's thing.

It takes about 40- 50 mins to complete.

Enjoy!
