Nav + 4 has the same features as UMI:
1 - Navigation with free live traffic

4 - AUX Interface
5 - Bluetooth Audio Streaming

The improvements to the system are:
5 times faster route calculation
5 times faster destination entry
5 times faster zooming

Updated navigation data

New functionality includes:

The NEW part number is A204 870 7096 and the MSRP is $1685 plus labor. The price could vary depending on the equipment already present in your vehicle. Also, it should be possible to upgrade an old UMI to the enhanced Nav + 4 with a software flash.
