Radio reception issues with double din

As for signal quality, its awful. I even loose radio 1/radio 2 and local stations are a disaster, loosing signal at various speeds and various locations.

Its quite frustrating as I listen to a lot of Radio 2 and BBC Radio Ulster/U105 locally.

Im going to try removing the splitter and using the normal ariel just instead and see if that helps.

Check your antenna amp has a +12 going to it, as well as your own idea to remove the splitter. Your splitter might well be faulty, if it works fine without it, but very badly with it in circuit. In circuit it should deteriorate, but not by very much.

Well ive already tried two other radios with it since and both dont have a built in amp, and they where 100% by comparssision, so im putting it down to the newer unit.

Just to clarify the signal amp when plugged in to the symphony set up gets its power from a connection in the iso block, ie from the back of the stereo, so if you swap the double din for the symphony the amp gets power you then swap back and the signal gets worse, some people may think it is the unit but as the signal amp is no longer being fed power by the head unit connection it is not working.

The best way to test if your amp is getting power is with a multimeter, if you dont have one unplugging the power to the amp should meke the reception much worse.

I will try and get pictures in my lunch break so people can check there conections and we can find out if some people do have issues with there units.

Hi Wutang,

Thanks fo this. For what it's worth, I'm still having reception issues, and I can say for certain that the anttenna amp is definitly recieving power.

In my case at least, reception is ok (not as good as the Symphony, but acceptable) without TMC, but once the splitter is introduced, it falls way below par. I think the solution is likely to be a "standalone" aerial for TMC, or possiblly some form of signal booster.

Yep same here. week signal even when tuned into the local radio station and the amp is getting power, even tried a different powered aerial and still the same, so it must be to do with the new units.

That worries me. Cant believe a system that is technically 10+ years ahead of a Symphony can give so much problems

It's a tad annoying !

To say the least Mark!!!! Simply I am not technically gifted enough to understand at all

Well the crux of it is that with there being two aerial inputs, one for Radio and one for TMC, both require a strong signal to work and splitting the signal we get from the rear screen aerial simply isn't powerfull enough to satisfy the needs of both things !...

There's only one aerial input on the back of my unit so I assume that I would need an additional aerial for the TMC side of things (think the TMC aerial provided with the unit is not up to the job) and that the aerial splitter is actually a combiner so that both aerials, i.e the OEM rear screen plus a new TMC aerial (Sharks Fin?), get fed into the one aerial socket on the back of the unit.
