    As a new owner of a Honda (my first foray into the marque) i've been very pleased with my recent purchase of a Honda Accord Tourer – except for one niggling issue.
    To be blunt, the radio reception is shocking.

    It works fine about 50% of the time but simply driving around a corner, or decending a hill, will see it turn into a wall of static and interference. Compared to my old Saab (which I drove on the same roads) it is hopeless. The Saab would either keep reception or retune via RDS to keep a strong signal.

    I've checked that the RDS is switched on, and I assume that the aerial is working, else it wouldn't pic up anything at all.

    Any ideas as to where to start looking much appreciated

    The antenna are built into the rear quarter lights in the boot, check the joiners where they attach to the aerial behind the trim in the boot, if the connectors get corroded they will lose a lot of gain and reception will suffer, check and clean with Servisol and maybe use some dielectric grease to prevent further corrosion.

    Thanks Bounder, that's really helpful.
    Just to clarify, is the antenna fitted in the actual boot lid, or is it behind the trim on the left hand side of the boot area?
    And the diagram you linked to shows that is the position of the sub antenna. There is a main antenna (part number 6) also shown, but no location info. Do you know where that is?

    If you look at the quarter lights the lines look like demister elements but are actually the aerials.

    I took the trim out of the boot and found the little box where the aerial lead joins the car's loom. The connectors were all immaculate. Clean as a whistle. I unplugged it, sprayed with some contact cleaner, wiped it off and plugged it back in again but no improvement.

    I'm wondering whether it is possible to fit a new aerial on the roof.

    There is two of those boxes, a main antenna 39155SEDJ01 and a sub antenna 39157SEDJ01, I wonder are they faulty?

    Are both boxes behind the boot trim? I only saw one – fitted just behind the nearside rear door under the window with the aerial in it

    Not really got any further on this. Reading up around the web makes it seem as if this is a fairly common issue.
    Driving back from London to the West Country last week I had to give up on listening to the radio and sat in glowering silence for the 4 hour drive, such was the poor reception. This showed me that it isn't down to poor signal in some areas, but is a deficiency in the car receiving the signal.

    So, is it possible to replace the standard window-mounted aerial with an alternative one? I'm thinking either a roof mounted one, or maybe one that goes inside the windscreen. All the ones I have seen for sale are equipped with a standard aerial plug, but looking at photos of the back of the Honda head unit shows that it doesn't have a standard aerial socket, so not sure how that will plug in.

    AN update again in case anyone has any more advice.

    I have replaced the built-in radio antenna with a powered auxiliary dashboard aerial from Halfords. Had to access the rear of the radio/satnav unit to unplug the old lead and plug in the new one. Ran the power lead for it off of the cigarette lighter power wire.
    I think it has made a minor difference, but reception is still rubbish compared to all my previous vehicles.

    Is it possible to replace the unit with a double-din aftermarket unit, or will this stop all the controls working?

    I had my 7th Generation Accord saloon for 10 years. I have driven around Barnstaple many-a-time and whilst there are some weaker reception areas, I have not encounted the problems you describe.
    I do not have the 7th Generation anymore, but have you tried altering the setting on the head unit?
    Does this happen with all stations?
    Are there any transmitter works/upgrades going on locally?

    Yes you can change the head unit. There are some who have done so, but it is not a simple task and some units won't pick up all the other functions.
