My car has got a CD30, but a friend of mine gave me a CDC40. Now i want to have an aux input with other things on the CDC40, and i'm thinking in buying one Parrot Mki9000. Anyone has got one like this?

I also have some doubts about the SOT connector and the leadings. If anyone could help.

I was thinking in buying that:

But there is one fully populated:

I'm a bit confused for which one to buy
