Hi all, I just installed the ottonavi on my 2010 Prius non jbl. Everything works great, however there is an issue with the volume control. It's either on mute or really loud. There is no level control. Has anyone had this same issue? For example, right from "mute", when I turn the dial, level one is really loud.
ANNDDDD, I just found the solution here. I swear I searched the forum before. "No your unit is not faulty Start the DVD app, you do not need to have a dvd in. Press the TUNE botton 4 times and rotate it to show "I.AMP" and dot "E.AMP"
