My 2010 Jetta originally had an instrument cluster with the simple white full size MFD without any phone information. At that time I had a 9W2 (the one shown in my previous post), as well as an RCD-510. The RCD-510 did not display any phone info.
The pairing, incoming call prompt, hang-up, muting, private mode, etc were all handled by an overhead button assembly (three buttons plus a green/amber/red LED). The steering wheel had no control buttons of any sort.
Calls were initiated by dialing on the phone itself. Answering was by the phone or pressing an overhead button.
Initial pairing was via an overhead button, but once that was done the pairing became automatic when the car was started as long as the phone was turned on at the time. (Or you could press one of the overhead buttons to make the car's Bluetooth "visible for 3 minutes" and pair a phone after the car was running.)
The simple white MFD that had been in my car meant that the overhead buttons were a necessity. This is because the simple white MFD will not show phone info whether or not there is a MFSW and a proper steering wheel control module.
With an MFSW the "phone" and "microphone" buttons can be used to answer and hang-up calls. But there is no button to use for initially pairing the phone. Some control method would be needed to search for and pair a phone. Either an overhead "pairing" button is needed, or a proper MFD instrument cluster selection method is needed. Without overhead control buttons it would be necessary to use a MFD to pair the phone.
My understanding is that your RED MFD will display phone info and allow pairing to a phone using the MFSW buttons, but only with a "1Z0 035 729 B" BT module.
I have also been told by a contributor to this forum that a "1K8 035 730 C" will work (i.e., communicate with a phone) in a 2009 with red MFD, although the MFD won't display the BT information because the CAN-bus data protocol is different (i.e., the red MFA+ does not use the BAP protocol
[Bedien und Anzeige Protokoll], but instead uses the Display Data Protocol
(DDP)). The phone pairing could be done in another car having a white MFD phone menu or overhead buttons, and then you could theoretically transfer the 1K8 035 730 C to a car with a red MFD and be able to use it with the buttons on a MFSW...but you'd still have no red MFD info.
See this site for good info on installing 9W2/9W3/9W7:

Here are a couple extractions...
9w2 bluetooth from Jetta, Golf, or Sportwagen (wagon) TDI
9w2 bluetooth lets you talk and receive but there is no phone book capability. You can still use voice control through your mobile phone to place outgoing calls, if equipped. It also has A2DP (bluetooth streaming music capability). An example of A2DP is wirelessly playing music directly from your iphone over the stereo. These were commonly found on 2010 Golf and sportwagon (sportwagen).
When combined with the RNS 510 GPS it does not display the phonebook over the touchscreen display.
Some part numbers for the 2010+ (white MFD) are 1k8 035 730 c (1k8035730c) and 1k8 035 730 d (1k8035730d)
The bluetooth antenna is internal.
9w2 VW bluetooth setup and use
2009 TDI with 9w2 with the red MFD should use part number VW# 1z0 035 729A [edit: I believe this info is slightly incorrect - the 1Z0 035 729 B is the proper "9W2" for the US market allowing the red MFD to show BT info]. 2010 and newer TDI with 9w2 and the white MFD 2010 and newer should use part number VW# 1z0 035 729 c and code 0011070. Others have reported 1k8 035 730 c. While you can't have voice dialing or a phone book menu in the MFD, if your phone has voice dialing you could open the Bluetooth and dial from the phone.
If your car came with 9w2 and the overhead bluetooth console, you lose its function if you install 9w3. 9w7 keeps the overhead bluetooth buttons active.
Initial Setup – “Pairing”
1. Switch on the customer’s Bluetooth-enabled cellular phone and the vehicle’s ignition. (This makes the Bluetooth “visible.” You must pair the system and phone within the five minutes it remains visible.)
2. Activate the Bluetooth feature in the phone and initiate a search for Bluetooth devices or audio enhancements.
3. Select ‘VW UHV’
4. Enter the Bluetooth pass code ‘0000’ on the phone. (On some phones, you will need to confirm the connection separately.)
5. Optional: To allow the phone and Bluetooth to connect automatically, set the Bluetooth system as an “authorized device” in the phone’s Bluetooth menu.
6. The Bluetooth system is now paired with the phone and ready for use. The pass code is not needed to connect the devices again.
Please see the user guides of the Bluetooth system and your mobile phone for more detailed descriptions.
Place a Call
1. To place a call, enter the number on your phone, or find the contact in your phone’s phonebook.
2. Press the green call button on your phone. The phone will immediately “ring” through the Volkswagen sound system.
Answer a Call
1. When connected to the Bluetooth system, an incoming call will mute the car radio and the ringtone will sound over the car speakers (if enabled).
2. To answer the call, press once on the phone button. You can now speak hands-free in your car and hear your call over your car speakers.
Ignore a Call
To ignore an incoming call, press and hold the phone button for more than 2 seconds.
End a Call
To end a call, press the phone button once.
Switch to Private Mode
To switch to private mode during a call, press and hold the phone button for more than 2 seconds.
If the phone supports “Advanced Audio Distribution Profile” (A2DP), music stored on the phone can be played over the radio or radio navigation system through the car speakers.
1. On the cell phone, select the music playback mode (such as “play via Bluetooth”), then select the device “VW UHV.”
2. Press the button on the radio or radio navigation system to select the media menu.
3. On the phone’s music menu, select the desired songs/playlist and press “play.” The music will begin The music plays on the Volkswagen sound system. When receiving an incoming call or placing a call, the music will pause and the phone call audio will be heard over the car speakers. When the call ends, the music will restart.

Or you could try this avenue for information...
Go to your dealer's parts department, give them your VIN and ask them to look up the BT module for your car. My dealer gets a display of all the modules available...including the newest ones. In particular, the VW parts system will generally stipulate the newest and most upgraded module which will work in the car.
And actually, the very first posting in this thread has some of the best info:
