I selected and held down the <Mode> button for several seconds (it was the right button for me).

i also love the buttons and the light on the charger, it makes going through music easier and a lot safer then trying to press the iphone's screen.so if you're looking for a iphone 3g fm transmitter that will charge, not bring up the annoying airplane pop up, and you don't live in or near any major cities, this is the one for you.

I reattached it with a rubber band so that it works to charge and play, though the buttons are inoperable (not a big deal to me as I use my iPod buttons)

The display numbers are very clear to see, even during the day and the buttons are easy to press without any issues

Press the middle button once then hold the right button for a few seconds then press the right button to select japan mode

The Autopilot offers a stronger and more stable signal quality, as well as navigation buttons on the cigarette lighter adapter

In addition to the faulty display, the buttons on the unit were cheap and wouldn't push down, so I couldn't perform any sort of reboot or diagnostics on the unit to try and get the display to work

While still holding right button press and hold preset middle button and release middle button and the right button at the same time

Then, press and hold the right button (which will say "Mode" above it) for about 5 seconds.
