Hey SIRIoz, I'm guessing you're after the Version Number e.g. Bluetooth v2.1 or Bluetooth v4.0 etc.
Sadly I cannot find anything about it on the web, even tried finding documentation to see if CarPlay requires a certain version. I can although find the new iPhone 6S uses Bluetooth v4.2 and the iPhone 4S, 5, 5S & 6 has v4.0
However, CarPlay is only compatible with iPhone 5 and above. There is a claim stating it needed the extra ability of the Lightening (cable) connection to run CarPlay. I have found articles that state the iPhone 4S will support the wireless CarPlay, not 100% sure the iPhone 4S will support CarPlay on iOS 9 though.
My point is, that to support CarPlay it might require Bluetooth Version 4.0 as a minimum, thus MIBII would have BT v4.0.
Also I have read the new MIBII system can do 2 paired Bluetooth phones at the same time! (might be one for music and one for phone at the same time, can't find much about that either).
Thanks Ralfi, I'm guessing 3407 is likely their internal version numbers. Although I'd love to think they are using the latest Bluetooth v4.0 standard or at least v3.0 and not v2.1. Bluetooth v4.0 has been around since 2009 and first introduced with the iPhone 4S. iPhone 4's used Bluetooth V2.1 + EDR.
If anyone has a way of identifying the Bluetooth Version the new MIBII (CarPlay enabled version) has I'd love to know! Still waiting for my car so I can't test anything.
Two things,
1. Can anyone confirm what Bluetooth Version (e.g. v4.0, v3.0, v2.1) the MIBII systems are using?
2. Can anyone shed anymore light on the 2 Bluetooth devices connected at the same time?
