How to change the fm frequency range on a kenwood dpx 400

SOURCE: kenwood dpx 4020

The iPod will stop itself from charging when the battery is full, and will not overcharge. I'm pretty sure you can't disconnect the power to the iPod (would stop it from charging) and still use the Audio to your stereo.

MichaelBlackDo you know where I can find the remote key combination to do the same with KDC-MP538U? (To transform it to the European system)

Thanks in advance!

I have a car stereo purchased from the US and I can’t pick up all radio stations in Europe/UK, what can I do?
If you have purchased a car stereo from the US you will find that it will not pick up many European radio stations. This is due to the fact that US radio frequency steps are different to here in Europe.
You may be able to set the tuner to European stations by following this procedure.
Press and hold down the SRC button to power down the unit completely.
While the unit is off press button 1 & 5 together, while momentarily pressing the SRC button.
If this does not work try the following proceedure;
Press and hold buttons 1 and 5 together, while momentarily pressing the reset button.
If this does not work then the unit is not designed to pick up European frequency steps.
