The Antenna sent by Euro Parts appears to be for a left hand drive car. Fitment on the passenger side (so that it does not obscure the drivers view) in a RHD car would have meant that the aerial would have been facing downwards instead of being upwards. I contacted Euro Parts for a return number and purchased the Antenna from another supplier. I have rated the Antenna with 5 stars because the correct item supplied by the other supplier works perfectly. I would say that the packaging makes no reference to Pioneer and the fitting instructions are non-existent. It was something you would expect to buy at a car boot sale. I would have taken a couple of stars off for the packaging but as the aerial works well I have left it at 5. Euro Parts took nearly a week to deliver the part, the second supplier 2 days. I am still waiting for a return number from Euro Parts so that I can get a refund.
