Re: 730N RER vs RHR--lany new info?
There's really no solid info yet on them. I don't even know that it's a different supplier, just an upgraded model.
I expect to maybe see them add to the RHR some features of the 430N RHB (the USB port in the console, the SMS compatibility, Bluetooth streaming, maybe even Sirius Travel Link), but that's just my own personal speculation. If it's nothing more than a minor change, then they're going to have a lot of confusion with the "cheap" GPS having features not on the "expensive" one.
