RCD510 Radio aerial Plugs different from RCD500 Help please!

[jackafrica]

Hi All,
I've bought one of the Chinese RCD510, works fine.
Would be perfect, with the 9W2 BUT

The aerial connections on the rear of the unit are a (ever so slightly) different configuration to the RCD500.

The RCD510 has the two aerial connections combined (I assume) meant for a single plug.

The RD500 has two separate plugs in the same way, but are much thicker.

Is there a cure for this which is easily effected?
Can the original plugs be shaved on their side to fit, or is there a connection available.
What have others done to meet this challenge?

I'm happy with the unit, it is great and does everything I could possibly want with the facility to play my music from the iPhone, etc.
But no radio makes Jack a dull boy If you know what I mean.

I look forward to finding a solution and all help is gratefully received.

Cheers,
Richard
