Author Topic: FM radio problem (Read 2428 times)

Hi,

My Jazz has the radio/CD with the big LCD display (not sure of radio model - 2005 car)

If I seek a station on FM, it maybe picks up 1 or 2, but there are loads of stations round where I live

Is there a way to set the sensitivity of the receiver?, or could it be an ariel connection issue?

AM is fine

Cheers

Alan

Sound like an aerial problem to me. The way I always used to check it was to slide out the radio; not sure how easy it is on that model; get a cheap few quid telescopic aerial and plug that in the back (you may need an adaptor; available on ebay or local motorist shop for a couple of quid).

If it works OK on that when held out of the window then the fault lies with the aerial or aerial cable. Sometimes the little aerial amp in the base of the roof aerial fails (if it has one) and causes very poor sensitivity.

Replacing the aerial on the roof can be expensive, especially if all the head lining has to be removed; I've heard of quotes well over £100 in the past so you need to check as above first. I've even heard of people using the cheap telescopic aerials and fit them on the top of the wheel arches to save the expense on older cars.

If checking with a separate aerial doesn't cure the problem then the fault is in the radio and you may need a replacement or repair.

P.S. I used to do car radios for a living before I retired.

Mike.

Hi,

Thanks for the advice

I changed the angle of the arial and reception back to normal so clearly some kind of connection issue

If it goes again, I'll try a more thorough clean and examination

Was the aerial lying too flat before ? They do work better when they are more upright - the normal 45 degree angle on the front mounted MK1 Jazz I believe is a compromise between reception and wind.

The aerial, vertical, gives the best signal and so, reception. The roof is the aerial ground plane. I have mine at the steepest angle I can, to clear the garage door, as I reverse in. It is adjusted to within a few millimetres of the door!
