I am willing to spend the vast amounts of hours it will take, I am just not ready to spend more then what I spent on getting the units through eBay. Plus since I'll get a fat discount from my local stealer,,,, additional required parts will not be too big of a deal.
I am just concerned if the whole thing will be able to work on my X5.
No I do not have Nav. on my X and will want to get it though...
