The 'out-laws' have a Zumo 550 (2009 maps - latest software updates) that they use to toour Europe with on a motorbike. Is there any way they can use an FM reciever for traffic (such as the GTM12 or 21) whilst still keeping the waterproof intergrity?
From what I have seen the USB port is mounted under a flap at the bottom of the device, which is impossible to use when in the bike cradle. Also, they have the power source mounted in the cradle atatched directly to the batter (no ciggy charger). The reason I was asking is because we want to get them a small gift, but we want it to be usable whilst riding.
