Extra Details

Universal for all Vehicles
The Radio Band Expander enables the original equipment radio in Japanese import cars to receive UK radio transmissions.
Electronic circuit with both active and passive connections
It achieves this by shifting the UK transmission frequencies into the band that the Japanese radio will detect.
Japan likes to be unique. So, the Japanese government mandated that Japanese FM operate from 76MHz to 90MHz. Which is, of course, different from most of the rest of the world, which operates from 88MHz to 108MHz. Because of this difference, a converter is necessary to make the FM tuners of Japanese Domestic Market car stereos work outside of Japan.
The FM Radio Band Expander Converter that we include with every purchase is an elegant piece of machinery that attaches in-line with the antenna input on the stereo.
12V + & - Very Important Positive/Negative Supply Connection
(Note there are other Band Expanders on eBay with one Positive (+) connection only, these will give you a interferences humming sound)
Receives all stations from 88Mhz to 108Mhz.
All circuits require both positive and negative voltages. A power supply must be used to provide each polarity.
The supply for positive voltage will have the negative terminal as a return, and the negative supply will have the positive terminal as the return.
These two terminals are connected together, forming a common return path for load current.
RELIABLE : each unit is individually precisely tuned for desired band on appropriate RF test equipment.
