Terrible Fm reception aftermarket radio/stereo

[Pinchlite]

I read somewhere the antenna has a booster and needs power.I have 2007 Yaris.Something about connecting blue wire to ?

Hopefully someone knows waht the issue is.The stock deck had fantastic reception.Thanks

there us a blue antenna lead like power antenna from your head unit. that should go to a blue wire from your antenna. yes the stock radio antenna needs this power to work.

I do get fm stations but very bad range/reception.I will pull deck and see whats up.Thanks for reply.

I believe I need to use the power retractable antenna wire from headunit which is 12 volts.

I dont see antenna power wire labeled on the stock yaris harness connecter.

Black wire I believe. Long time since I'd done mine.

Should be blue or blue/white. I always get them mixed up. Your aftermarket head unit should only have 1 though. If the adaptor harness has both of those, just connect them both to the one.

I used the power antenna power from headunit to blue yaris antenna wire.

I did this but no difference in reception.

I will try somesort of antenna booster/amplifier and if that doesnt work then I will get better headunit.Actually tempted to put the stock unit back in.

[Pinchlite]

Yup.

Did this and no change.

From what I have read Its a known issue just not with yaris but other cars aswell using aftermarket headunit.

my headunit is a good quality Pioneer doubledin.

I just dont use the radio.

I did this but did not improve.
