Hi,
Would just like to let you know that the Dension Gateway 300 is installed and works a treat, I have got the CD retention cable working aswell
Theres a good vid on youtube on how to replace Z4 headunit, pro for seeing how to remove vents etc.

I put the dension underneath the headunit as there was a big space to seat it nicely with some velcro pads so it doesnt move around. I put the CD retention cable behind the headunit, tucked away nicely. I then ran the USB, a 3.5" jack and the ipod docking station into the glovebox, so its all hidden away.
This job took a bit longer as had to run a thin cable from CD retention cable to the CD changer, but was easy to do by running cable underneath the trim along the drivers side where the gearbox is, (used a small screwdriver to poke wire up out of view under trim).
I then took off the speaker cover behind the drivers seat, went in from the boot (had to make a small slice in carpet where emergency release cable for roof is to slide button through & remove tv tuner) to see how to get through to the cockpit. ( I dont have DSP)
Poke a metal coat hanger through from the boot to where the speaker cover was off, then pulled through the cable and connected to the cd changer, then put everything back.
Make sure you test everything before putting everything back. I even went to the extent of taking the car for a drive before replacing the vents etc to make sure I hadn't created any rattles
I have tested it with the Sat Nav and you
CAN have text but I havent tested the full capability, I currently have the album name showing, but if MP3 is what you are after, you cant go wrong with this bit of kit, it sounds superb.
One thing I have noticed with the text enabled is if you try and close the sat nav screen when it is displaying the mp3 text it wont, you have to select a different display e.g. computer menu and then close it, but thats not really an issue.
I am still trying to get to grips with how to navigate through albums and tracks etc, but so far really pleased as USB stick is the way to go, and its a bonus not having the music jump when you hit a bump.
The USB stick I use is an integral 8Gb standard cheap one. I copied albums into folders on the stick.
One thing that I did find was that you can download a Gateway indexer for your PC that will do the indexing of your MP3 on the stick before you connect it to your car, so your dension doesnt need to do this when you first connect it, this is good practice for large USB devices with a monster amount of mp3's.

If you are thinking about how to get MP3 connectivity, I cant recommend this enough, as I now have all audio inputs available, I havent changed anything with the BMW stock unit, so when it comes to sale time it will have all the factory fitted extras with MP3 playback as a bonus!
Ipodcarkitdirect - I ordered from this site, and when I logged in to see the progress of the order it didnt update at all. So I contacted them and asked the situation with my order, where they told me it had been shipped, although on the website it still said processing. They told me that the status on the website was for their use rather than mine........... at least I received the goods, and the contact via e-mail was very good a person called Dave, but I have heard bad things aswell, so I did have my concerns. When the package turned up it was from a company called Daltec Ai Ltd, there was no paperwork with order.
But thought I would let you know as im sure I saw a post with a fellow member having problems.
Thanks to everyone thats contributed to this topic, especially Mangozac!
