Hi All,

I'm new to the site but have to admit its very impressive the amount of info that’s on here.

I have recently bought an X5 late 2004 4.4L in Sydney Australia.

Essentially i have a couple of questions that im hoping you can help me with, i have done the searches and still have a few questions.

1. Are the 2004 cars prewired for Nav, i have the 16:9 monitor already installed (from factory) but am unsure if i buy the nav unit i can just find the loom and clip it in.

2. If i need to install a new loom is it just a simplified loom to the monitor from the computer, or do i need to replace the entire loom and connect all the bits and pieces, e.g. CD stacker.

3. There are some great instructions on here about doing the full install including the 16:9 install, does anyone have a link to doing a simple computer install and possibly running the loom?

4. Just trying to figure out if the Mk4 comp is that much better than the Mk3? Its twice the price on ebay, and seems to be just a little faster. Is there any real reason to spend all the extra money?

5. As soon as i connect the Nav computer will the monitor automatically give me the navigation options too?

Thanks and really appreciate your help.
