New pioneer deh-p4800mp doesn't work

I'm trying to fit a Pioneer DEH-P4800MP CD Player in an old (1990) Honda Civic. Should be straight forward but the unit will not switch on despite 12V (via the yellow 12V constant power cable, i.e. not routed through the ignition accessory switch) correctly supplied to the ISO port at the back and 5.2 V available at the control unit interface at the front. Is the control unit faulty or am I missing something? If the former, is there a way to check it? Any advice greatly appreciated. jc

How about the red (switched power) wire? The unit will not turn on unless you have 11+ volts on the yellow AND the red power leads.

I have a Pioneer DEH-p4800mp and I connected to amplifier when i stop the cd player does not stop the amplificator

Question? have you also connected the Remote cable from the CD player to the Amp? or have you only got 12v & gnd hooked into the amp? if so then the amp will be on all the time. the remote goes from the CD player to the amp, usually a blue cable from the back of the head unit.

New iTouch doesn't work in DEH-P4800MP

The newest versions of the Iphone uses USB charging only, while older generations of (any) Ipods used firewire for charging. First generation Iphone and Ipod Touch could be charged with either method. Most docks historically used the firewire charging method, making them incompatible with all but 1st generation Iphones. You need a new cable/charger that charges with the USB method.

Yes it does, I have proof.

Open a new window/tab browser. Click this link to the PIONEER WEBSITE PDF File for this cable. Please refer to page 7of 84, and look in the category "head unit group 1"... From the BOTTOM LEFT of this paragraph count up FIVE LINES, your Head Unit Model number is right there.

I hope this helps,
