Stereo Dilemma.

09 April 2013 - 08:54 AM

Hi folks.


We recently bought a second hand S Max ST which we're really pleased with, except with the stereo.

It is an after market Chinese unit which does everything (including digital TV) but all we really want to do is listen to the radio and play CDs.


The FM reception is lousy - unlistenable even on the station transmitted from about three fields away (Heart Essex). A local guy came out yesterday, pulled it out and took a look but couldn't help matters, and removed £55 from my wallet for his time (fair enough, but from my perspective I don't want to waste any more money on it).


With the head unit removed, the wiring all looks fine and the aerial is connected. The only ray of hope I had was a blue wire which said `12v' and wasn't connected to anything.  I was sure (wishful thinking) this was going to be the supply to the aerial booster, and simply connecting this to the aerial cable would send 12 v back up to the booster and fix the problem.


The professional who came out told me that this was not the case, and that the 12v was sent up straight from the head unit through the centre core of the aerial.


I am now wondering if the head unit is actually sending this 12v up the aerial if it is an aftermarket one? If it's not then obviously an unpowered aerial booster will block most of the signal from the aerial and cause the dreadful reception. Perhaps I should just disconnect the booster which I believe is located in the void above the quarterlight window, which is where the aerial is. I took a look but wimped out as it looked quite close to an air bag mechanism and I could just see me creating another problem!!


I know the head unit is not good quality. My guy has told me the unit is at fault, and quoted many dollars to replace it with a more basic but higher quality item. It might be that someone on here has been in this situation and can offer some advice?


Thanks in advance for any help

Hi everyone, I'm Nick. I'm based in Chelmsford, Essex. We have just bought a second hand (57) S Max 2.5 ST which we're really pleased with. It is a bit better than our previous vehicle - a Citroen Xsara Picasso!


Have just one issue with it, I'll try to find an appropriate part of the site and start a thread about it.
