Title: No radio signal ?
Post by: omega3000 on 10 November 2013, 17:18:01
Fitted a new cd/radio today . Everything works accept cant get any signal to the radio  :( There is a red wire coming off the Arial wire and dont have a clue what this is for . Worse case scenario would be to fit a new arial lead and arial but dont really want to be doing that .
Any idea . Car is 1998 p/f 3.0 MV6 .

TIA

IIRC it`s the switched feed for aerial amplifier

Yeah, if it comes off pin 7, its the remote switch on for the aerial amp.

Tried it connected to switch live,was nothing  :o
The wire was part of the aerial lead and a new connector for aerial was also fitted to the original wire already

Is the replacement HU a GM one? If not, is the pinout the same (unlikely)?

He had an Alpine h/u fitted to the car i bought then he took the Alpine h/u out before i went and picked it up . I bought a brand new Sony h/u and fitted that today . Now there is no radio signal  :y

I bet he was pleased. Use to a Sony, then was able to listen to an Alpine. And to top it all, some mug bought his Sony ;D

Looks like it will be aftermarket arial fitment then . Or i can take it back for full refund and get a different h/u  :-\ :-\ :-\ :-\

Ok mate  :y

I dont see what the issue is with using aftermarket h/units though . I can easily swop it for a brand new Alpine unit but what difference is that going to make  :-\ :-\

The issue is that you need to find which pin your new HU uses for 'Antenna' or 'Ant' so it can power up the aerial amplifier.

The basic ISO connectors (speakers & power) don't vary much from manufacturer to manufacturer (except that VX swap the switched feed  ::))

Ok Andy thanks . So it could be possible that a different aftermarket head unit would indeed work . May just be the physical connections .

Ive got a spare loom to try from a different h/u will see what that does .

Hmm, swapping random parts. The chances of it miraculously having the correct wiring are close to zero.

How about you tell us what model HU so we can check the pin outs?

The adaptor lead would have cost less than the fuel and buggering about time had you bought one with the radio...

Would/should have been plug and play ::)

TBH, as Sony HUs are unbelievably crap, crappier than a crap crap, you've done the right think. A Goodmans would be a better choice ;D

But you'll be unlikely to find a non factory fit radio that will just plug in.

Rather than bodge and shag the car's loom, always use an adapter, and make the modifications on the adpater.
