Hi Owen,
sorry to hear about your problem. Generally this is not an area that the Disco II suffers a problem.
Generally, bad radio reception issues arrise from aerial problems, a poor earth/ground for the radio head unit or a fauty reciever unit within the head unit.
The Disco II uses an aerial that is mounted into the right hand rear load space window glass - it looks like a demister wire. This wire is of a tuned length to provide the optimum signal pick-up in each market. In the roof above the glass (concealed by the roof lining) is an aerial amplifier which is used to enhance the signal. From here, a co-axial cable runs straight into the rear of the head unit.
Is you vehicle fitted with window tint? A lot of window tint films contain a metal base to provide their blacking-out effect. If this is the case, the benifits of the tuned length aerial wire are lost. This type of window tint will consequently effect your radio reception.
To test for a fault in the aerial system, it is possible to remove the radio head unit and plug in a standard (external vehicle type) radio aerial. If this improves the reception, it confims a fault in this side of the system.
The radios fitted to Disco IIs in Australia are the same as those fitted in the UK. It may pay to ask your dealer to swap a head unit from one of their demo vehicles to rule out a problem with your unit's internal reciever.
It is also sometimes possible that particular stations in certain areas are not conducive to fantastic radio reception. To establish whether your vehicle has an isolated problem or not, it may pay to take another Disco II with the same radio to the same places that you suffer an issue and compare them.
Good luck.
