I have just bought a Sony CDX-GT620u head unit to go into my 54 plated Picasso.

I have looked all over the 'net on installation guides and I thought I'd followed it pretty well, however when it was fitted the reception from MW was non existent, and although I haven't had much chance to test it the reception for the weaker FM stations isn't exactly brilliant either.

I've had a look (again) on the 'net for other people who have had this problem but all I can find seems to point towards VW based cars (VW, Seat, Skoda etc.), even though the problem experienced is exactly like the one I'm having trouble with.

I'm sorely tempted to go and buy one of these from Hellfrauds but I don't know if it will be a waste of money or not. I also feel that my problem is so 'trivial' that any I.C.E. specialist won't be interested in solving it.

So can some one here help please?

Thanks
:D

Sorted.

:D

I found out from my local Citroen dealership that the aerial carries a very very small current and as such needs a power source. With the factory fitted stereo that is internal but with Head Units such as my Sony you need an external power source.

It took about 5 minutes to plug it in and wire it up and I have to say that the M.W. reception is fantastic.

I'd recommend this solution to anyone.

Wow, another "improvement" in vehicle electronics, eh? The head swap on the X-reg Pic required no such farting-about, and the radio performance was absolutely fine..........unless that was nothing to do with the head unit itself, but that I was using the full Autoleads harness set, of course.

Powered aerial? When I were a lad, we were lucky if we 'ad a bent coat-hanger.

I now have the same problem after putting a Panasonic unit into an 02 Pic. You don't mention which lead is the one supplying the Aerial as my unit has a spare power supply lead for this sort of application. It also has a lead to connect to a separate remote like the steering wheel controls so if anyone out there knows witch lead to connect to on the car it would be helpful.

Hi,
I have found that the factory fit aerial falls out quite easily when swapping HUs. There is not so much room with all the connectors at the back when pushing HUs in. I had to remove the air vents to get my hand in to push the aerial plug in. Check the connection before spending money :)

My replacement head unit now crackles like mad on FM when I press the rear screen/wing mirror demister button. Any ideas other than "don't press it"? ;)

No crackles when playing CD, MP3 or SD card. However, when I tried a USB hard drive on it the aircon swiched off power through the USB socket for some strange reason.

I'm thinking earth problems.

Flick up the little end flaps at the side of the radio, this exposes the screws, undo them then just pull. Sorted.

Just read this about the power supply requirement for the aerial.

When I replaced my head unit to a sony I did not notice a power lead for the aerial. My reception has got noticeably worse with the new sony head unit and feel i'm constantly pushing the tune button to find a better signal, but then I do travel the length of the country every week. .

Has anyone else found this??? or is it me?

The aerial unit on the Pic being roof mounted at the rear of the car has an internal PCB. However there are reports that some cars suffer from board failure due to water ingress around the aerial onto the board beneath it. I have not had a problem with my Pic or my two C3s (same set up). So maybe you need to look at the aerial end of the car. Haynes wire diagrams don't show a power feed to the aerial but it could be sent down the aerial lead and decoupled at the ends, IF IT HAS power that is. i recall that pic access is via the rear light in the boot space roof??? (don't own Pic now so can't check)

I had the same problem on my picasso in that when I fitted an aftermarket stereo it would not pick up mw whatsoever and fm was iffy. I sorted mine by completely removing the pcb board on the aerial mount and connecting the aerial wire directly to the aerial without having to buy/modify any parts. Hey presto, mw and fm all work perfectly.

What is the best way to get to this pcb board/ is it located by the boot internal light on the roof at the back? if yes, is there a diagram to show this? where can i find it?

Thank you

Yes its located on the light at the back, however all I see is a silver circular disk, I can't even see where the lead attaches to this.

I could do with a bit of help as to how to bypass (what I assume is) the pcb.

Ignore the post above. I solved the weak reception by getting a new aerial from ebay. All working now.
