I have a pioneer car stereo model FH-P6050UB i took it out of the dash just popped out as i just needed to put the antenna lead in which was slightly loose now the stereo won't turn on have checked there is power going to the unit and all fuses are ok any idea on what could have caused this?

Check antenna connection on back of stereo also check the antenna lead for the car sometimes the inner core of the antenna lead gets moisture ingress.

The deh p6050ub does not play DVD's. You can add on a DVD player and control it thru the Pioneer. The Link above is for the owners manual. Page 59 describes the use of a DVD player. If the link does not work, do a search on the web " Pioneer deh p6050ub"
for the manual.

You need to buy a wiring harness compatible with your vehicle. The wiring harness will connect to your vehicle OEM plug and the other end you need to splice it with the wire that came along with your car stereo.

Your manual is here it will tell you exactly how to setup your deck.
Too much to type and this will be more complete.

Hi, see page 27 of the user manual here: http://www.boomspeed.com/melissaseow/FH-P6050UBManual.pdf

Hi there,

Well you can please follow the below steps -
1. Disconnect your car battery. It is vitally important to your safety that you never work on any type of electronic in your car with the battery still connected, as this puts you at risk for electrocution.
2. Remove the old stereo by taking off all the dashboard panels surrounding your stereo, sliding out your old stereo head unit, and unplugging all the wires that are connected to the head unit. Discard the old stereo.
3. Take your Pioneer car stereo head unit and plug each of the positive wires from your car speakers to the positive terminals on the head unit. Take all of the negative speaker wires and connect them to the negative terminals on the head unit.
4. Attach the stereo's black ground wire to a metal bolt or screw located near where the stereo is mounted in the dash.
5. Connect all of the ignition power wires to your Pioneer stereo.
6. Take the harness connector and plug it into your car stereo. Now plug the antenna into the back of your head unit.
7. Slide the stereo back into the dash, screw it in place, and replace the dashboard pieces you removed earlier.
8. Reconnect your car battery, turn the car on and test out your new Pioneer car stereo. Please post comments for more help or information..........

Good Luck!!

Thanks

I have just taken a look at the pioneer website and the jack you are looking for is at the rear of the unit. type your band in to google and it has all the info on the unit and pre outs for AUX, Has the unit been installed ?
