I would recommend that you get a newer ULF module than is offered by EIS kits. Look into getting the 9th generation ULF module or newer. EISKIts sells ONLY the first gen ULF module.

try http://www.europeanautosource.com/ as they have the latest ULF modules and very good support

you can retrofit the assist/BT combo but the modules are $2,700! and you can NEVER get a snap in adapter for any phone even if you upgrade.

Snap in adapters are only an option with the Bluetooth/voice recognition module OR for the X5 X3 2005 and up
