Just so no one is mislead...
There are two styles of white full size displays used in the 2010 Jetta sedans and wagons.
If you see an overhead line drawing of your vehicle in the center of the instrument cluster which indicates open doors, trunk or hood, then you have a Hi-Line instrument cluster with an MFD+ display. If you do not see this pictogram of the car when you open a door then you have a Lo-Line instrument cluster with an MFD display.
Whether you have an RNS-510 or an RCD-510, the Lo-Line instrument cluster with a white MFD display will not show any phone information when the 9W7 is installed.
If you have a Hi-Line instrument cluster with a white MFD+ display, all the "PHONE" menus of the 9W7 will be visible whether you have an RNS-510 or an RCD-510.
If you have a Multi-Function Steering Wheel and a Lo-Line MFD you can still access all functions of the 9W7 via voice commands. This includes commanding the Text-to-Speech (Text Recognition) system reading of your cell's phonebook and the recording of custom voice tags for each entry in the phonebook. (Note, however, that your cell phone must have the ability to transfer the phonebook info to the 9W7. See other threads for info about which phones can and cannot do this.)
BTW...the overhead LED light operation with the 9W7 has still not been resolved. We are waiting for the 2011 models to arrive with the 9W7 installed by the factory. Those models may or may not not have an overhead BT phone control console with or without an LED.
As much as I originally liked the idea of an indicator light confirming the pairing of a phone to the 9W7, I don't miss it at all since the RNS-510 and MFD+ keep me informed of the BT connection status.
