dvd90 navi bt and aux

[Ahermann]

hello everybody..i culd probably find ansvers somewhere on this forum but i have looked for a while and figured it is just better to ask straight out and hopefully get som good ansvers..


question 1: my 2007 vectra 1.9cdti cosmo has a dvd90 navi in it and color screen,but no bluetooth... as it seems it should be able to handle a phone it would be nice to ad one if possible.
can i just buy a uhp4 and connect it? what would it take to do so?
would be nice with a "walktru" in what would need to be done.

question 2. this car does not hav aux input,can that i simple manners be connected? what would that take?

hope for som good ansvers
thanks
