Re: 730N - RER upgrade to 730N - RHR
From what I see listed in the features of all three media centers, the only one with "Lane guidance feature guides you to the correct lane for an approaching turn or exit, making unfamiliar intersections and exits easy to navigate " is the 430N with Garmin software. I do not see that either the 730N RER or the new 730N RHR will have this feature. If you have ever used a Gramin stand alone GPS you can appreciate how important this is. Maybe the Harmon units have it and it is just not listed, I don't know. Maybe someone who has actually used the 730N RER can tell us for sure.
