On 4/2 , I bought a 2005 BMW X5, it has Sirius, single in-dash CD/mp3, BMW Assist, Bluetooth, & a DVD player with monitors in the headrests. I have a few questions, and have searched these forums but haven't really found the info I'm looking for.

1. I believe that the 2006 Business CD players have ID3 tags and folder navigation, does anyone know if I can have my dealer swap out my single CD/mp3 for the newer model without affecting any of the other features (i.e. phone, Sirius, etc)? I suspect that this is my only way of keeping the features I love and adding the ones I need.

2. I'm new to all of this, and I'm also wondering why my steering wheel doesn't have the ability to go through the modes on the radio (cycle through CD, AM/FM radio, Sirius, Changer, aux input, etc). That's another feature I would really like.

3. If I get the folder navigation, my next step would be to be able to navigate through the folders from the steering wheel. Can this be done?

4. Can I get a remote control for the radio? Sometimes my husband is driving and I really want to change the radio station from a remote.

Am I being too picky?

Thanks for any info you can provide me.
