Hello, in my car I have a regular radio that I want to change to a
radio with cd or dvd player, something more modern, but as I am totally
clueless at these sort of things, I thought I might get some help here.
Basically my most nagging question is, if I buy online a car radio
(ebay or amazon or any other place, since I'm living in a rather remote
and expensive country to buy it locally), how will I know whether it
will fit correctly in my car? Are these standard sizes or only
particular radio types are going with particular car makes? Is there
anything else maybe that I should be aware of before shopping?
Hope my question doesn't sound too dumb but I'm new at this thing and I
want to learn.

Thanks!
