My JVC KD-S590 was working until I drove over a somewhat bumpy road, and now I cant get any sound from my speakers.

Hi,

scm might stand for skip-continuously-mode where songs play in no particular order. To be sure, we would need to look at the list of modes in your device's manual. These are where all acronyms are usually explained.

Thank you.

take a digital volt meter and check the power cable and ground on the amp to see if you are getting any power . should read 12.5 or more if no power then check fuses and the ground connection

if you have power then replace the equipment that not working

Press and hold SEL (Select) and Adjust with volume up/down and move from hours to mins with next track/last track

HTH :)

Just found a manual at

looks like im close, but have no model to test with sorry

To switch from front to rear speakers you need to look for FADER option.It would be under main SOUND menu.That will of course work if you got rear speakers hooked up.

Step by step included, change clock on JVC KD-s590 KTC- 4th Mar 2005 4:00 Setting the clock:

1 Press and hold SEL (Select) for more
than 2 seconds.
“CLOCK H”, “CLOCK M”, “SCM LINK” or
“LEVEL” appears on the display.

2 Set the hour.

3 Select “CLOCK H” if not shown on the
display.

4 Adjust the hour.

5 Set the minute.

6 Select “CLOCK M.”

7 Adjust the minute.

8 Press SEL (select) to finish the setting.

sounds like only the constant(yellow) wire has power. you need to make sure that the switched wire(red) has power as well. good way to trouble shoot, is to hook the red to the yellow to see if it powers up then, if so you know the radio is ok, you just need to find a better power source for the red wire. hope this helps.

try to check the transistor and resistor

Here you go second to last page showes you how to hook up.

you need to have whoever installed the unit connect the YELLOW (memory) wire on the back to a constant 12 volt power source. It is hooked up right now to only have power when the key is on. this is why when you turn off the key, you loose memory.

what kind of car is this in... I can tell you what wire goes to what color if you cant figure it out.
