For those of you that still have a 550, and lament the fact that its got the wrong bluetooth chip fitted,
there is a workround that will give you stereo MP3 and NAv audio, snap crackle and pop free
https://www.ebay.co.uk/itm/Wireless...435551&hash=item3d4f227d24:g:tUgAAOSw8UZaCRMy
Pair with your headset, and plug into the speaker output on the Zumo cradle
Clear Stereo Mp3 audio and Nav instrucions
Claimed battery life is 5-8 hrs
Only downsides i can see is that you dont get the flexibility of say spotify and its track selection. and that you can only fit 4Gb of Mp3 onto your memory card
