i got the call waiting update (ITB10-066b) applied to my 2010 G37, this update looks to only be for 2010 and up Gs...
i thought id share this with everyone, as the OP thread is focused on another related issue for his G25.
APPLIED VEHICLES:
2010-2011 EX35 (J50) – with Navigation

IF YOU CONFIRM
One or more of the following is occurring on an Applied Vehicle:
• Audio streaming via Bluetooth is “choppy” or “clipped.”
• “Calculating Route” takes an extended period of time (2-5 minutes) to complete.
• “Could not find a route” displays when attempting to calculate a route.
• Voice Recognition sequence takes too many steps.
• Voice Recognition has difficulty recognizing voicetags.
• The Navigation system reboots.
• XM NavTraffic is slow to report.
• “Handset Phonebook” access is slow.
• When a hands-free call via Bluetooth is in progress and another call comes in (“call waiting”), there is no function available to answer the incoming call.
NOTE: The original specification for 2010 and some 2011 Applied Vehicles did not include the call waiting feature. To ensure a high level of customer satisfaction Nissan has enhanced the Infotainment system in many 2011 Applied Vehicles to add the call waiting feature. Nissan is making available this same enhancement for all Applied Vehicles by offering the call waiting feature as part of the Reprogramming Software DVD update listed in the Parts Information section.
• Caller ID is not available when a hands-free call via Bluetooth is in progress and another call comes in.
