Ours a 2008 Jazz, and one of the cheap chinese bluetooth dongles works fine - it's one of the small blue cased ones which are very cheap (often less than £3) from Chinese sellers on ebay. Of course you can only access the engine with OBD. In fact, I have a few ELM327 type cables and the Jazz works with all of them.
FWIW, I have also been playing with an old version Honda HDS v2 clone cable, and although the Jazz is available in the software, it doesn't seem to connect to all of the car's systems. I believe the later, more expensive HDS v3 clone works 100%.
