When I did my search for an iPod/iPhone integration system for my X5, I was shocked that the system from the BMW dealership was limited and about 1k for a full integration with installation. After much research, I found the full integration system that I was looking for on eBay and saving roughly $700. I was and had a lot of speculation regarding purchasing this unit and wondering about it's full functionality. As my re-search brought me back to the BMW dealership, they didn't even know of the DICE integration system existed and couldn't answer all my questions I had regarding installation of satellite radio and a iPod/iPhone integration from the dealer saying that "I was limited and it would be spendy".

I completed my research on the full DICE integration system and purchased it from an eBay member who owned a stereo shop, I asked him many questions, he backed the product and said if I didn't like it, he'd refund my money 100%. I had a professional shop install it per the warranty from which I purchased the system from. It's an easy install (Plug & Play system) The units firmware is easily updated by your laptop, a USB to micro USB adapter to the SC-C1 unit from your wireless laptop using DICE's support and update menu for the model purchased.

I've installed the DICE Sirius unit and SC-C1 integration system into my 2004 X5 3.0L with DSP but without a Nav or CD changer system (But have a separate Single CD player in dash and LOVE IT! I have full integration of the steering wheel buttons for Satellite Radio, iPod/iPhone, CD and FM Radio.

They make a unit that supports use of the NAV system if you have it. Either way if you have a a model with a separate CD changer, it may have to be removed in order for this integration to be installed properly.

Why pay a high dollar (3rd party) for a BMW factory use integration system when you can purchase it for cheaper without paying dealer prices and installation? My $0.02's worth.

I've been nothing but happy with this systems full use of Sirius radio and it's integration of the iPod/iPhone cable from unit. It's easily hidden and also charges during operation.

It's obvious I can't say enough about it.

In the beginning DICE had some issues with it's set up and usage, While they were working out all the bugs and testing the new firmware, updates were announced and installed as needed. Since... I have yet to install another update in 8mo. checking frequently. However, they are all about the customer! Taking care of any installation issues or of it's integration operation. It looks like DICE was just purchased by Audiovox. I'm hoping that the same support that I received by dealing with DICE direct hasn't changed.

Since my last Firmware updates and working with them, I have yet to see any minor link issues regarding my Satellite Radio linking or loss of settings to stations. I've never had any issues regarding iPod/iPhone usage.

It's important that you know your current system before "Just" purchasing an integration system. You need to know if you have NAV or not, DSP or not, CD Changer or not etc. There are types of units specifically made for having or not having those items. Of course YEAR/Make and Model of your vehicle
