I am trying to find out what is the maximum Bluetooth protocol level that the 2015 Prius C will use (if it matters, I have the "Two" trim, without the Entune system). I understand that Bluetooth devices are backwards-compatible; I know that if I have, say, a Bluetooth 4.1 device, then it'll still work even if the car only supports Bluetooth 2.0 -- but in that case, both the client and the receiver will speak Bluetooth 2.0 to each other, since they fall back to the lowest common denominator. I am looking for the maximum protocol level that the car will actually "speak".
Page 322 of the 2015 Toyota Prius C Manual (part # OM52E68U) states:
Ver. 2.0 or higher (Recommended: Ver. 3.0+EDR or higher)
This is the only information I could find that even suggests the maximum version of the Bluetooth spec that the Prius C actually supports -- it seems to suggest that 3.0 + EDR is supported. However, it doesn't actually come out and say that it supports 3.0.
I am mostly interested in seeing if it actually supports things like:
- Bluetooth 4.0 Low Energy (LE)
- apt-X or AAC audio codecs
However, the manual doesn't state it, so I'm left to either assume that it doesn't support them, or maybe it does and the manual writers didn't get the memo.
