Today I received my Intravee II from BMWNav. The cost was $250.

I am waiting on the an Alpine KCA-420i, which I ordered last week from Sonic Electronix. Delivery is scheduled for tomoorw, and the cost was $90. It was harder than expected to find this device on the web as it appears to have had its hey-day around 2004-2006 (based on productr reviews), and inventory is down or it has been discontinued by most retailers.

I opted for this configurtation over DICE due to ease of install and the interface. Assuming I don't need to update my Intravee software, it appears installation is about as simple as a DIY job can get. Once I have it all installed I will provide my review.

BTW, my car is a 2006 X5 with DSP and Nav, neither of which matters much with the Intravee confirguration I gather as it uses the 3 and 6 pin connections, not the DSP coax.
