CD player question

[slygeo87]

Here's the deal:



If I buy a CD player like this one for example:



...where can I put it?According to this image above, could I place it in No. 1, No. 2 or No. 3?Can I choose where will I place it for a simple cd like that?

Another a question...in case I want to place something like that:



...in which place of these three spots will go?As far as I can imagine the man who will fix it for me will take off the plastic in No. 2 & No. 3 right?Above the ashtray and below the A/C.

Please answer my questions...
