Setting the clock on a JVC KD-G420 in dash CD player – This definitely falls under the “way harder then it needs to be” category. Months ago, I replaced the battery in my old bronco and reset the clock on my CD player. Normaly, this would not be a problem except the designers of this particular device decided it was better to have cute flashing lights, lots of buttons, and constant advertisements (Gee, like I forgot my stereo has an Aux input and I need to be reminded every 15 seconds…) then a usefull user interface.

Anyway, to set the clock… (While the unit is on)

1. Press and hold the S (or SEL) button for a while until the display reads DEMO (usualy)
2. Turn the volume knob until the display reads DEMO OFF
3. Press the v|<< / >>|^ button (yes, that’s what it’s called in the manual) until the display reads CLOCK H
4. Turn the volume knob to set the hour
5. Press the v|<< / >>|^ button until the display reads CLOCK M
6. Turn the volume knob to set the minute
7. Press the S (or SEL) button to save

I guess I could add a step 8 here: Bookmark this post because you may not remember this sequence 6 months from now when the time changes and you have to reset the clock.

By the way, I found the users manual (in PDF) here.

When Vista forgets the display settings, you can try the following (from Microsoft TechNet Forums Post by Herb Caudill)

1. Go to Windows Mobility Center (win-X) and click Connect Display.
2. Choose “Show my desktop on the external display only”
3. Click OK
4. Go to Display Settings, extend the desktop back onto your laptop display, and position everything the way you want it.
