Hello everyone. As you can probably tell, I am new here. I just bought a 2007 Ridgeline RTL w/Nav and I am having a couple issues. Firstly the Nav part won't work. I have the touch screen radio that is shown in the owners manual with all the buttons at the bottom and a flip out screen. (No volume knob or anything, just buttons) When I press the Navi button the Navigator starts and the loading bar fills. Once it is full it stays on that screen for about 5 minutes and then just exits. Back to music. I don't know what the issue is or why it does this but I was hoping maybe one of you great wonderful people might. My other issue being also with the radio, the steering wheel controls do not work. Cruise control works fine and everything on the right side, but the volume up & down and mode buttons do nothing. Any help is appreciated. THANKS!
