Hi, I'm new to forum.
I have just bought a pioneer DEH-2700UI stereo to fit in to my 04 punto (still has original tape player) but cannot get it to power on! Have tried switching wires around, but nothing is working!!
Would really appreciate it if someone could help?!
Thanks
ugh..... right here we go again
Punto mk2 2004 - Mk2b with a canbus radio
The stock stereo has
1 power feed (constant)and 1 earth, there are 2 thinner canbus wires H and L
these 2 wires are more like 12v data lines vs 12v power lines, and SHOULDNT BE TOUCHED/connected to the new HU
The car tells the stereo when to turn and off

Your new stereo has
2 power feeds, Constant and switched and 1 earth
Your original constant wire that powered the current stereo wiring, needs to be connected to the new HU constant wire as well, otherwise you'll not
A - power up
B - keep any setting like clock or radio stations
So your asking - how do i have 2 power feeds? Preferably the missing switched feed
You need to use a piggyback fuse in the cigarette sockets fuse (in fuse box)
Or you need to cut and solder and heatshrink to the actual cigarette socket
this then needs to run behind the dash and up into the back of the HU wiring, to be connected to the switched feed position
See here about this
Mine has been wired like this for months now, no issues, just simply requires the key to be on ignition for it to work, nothing you cant do about it, unless your willing to live with flat batteries every morning
