I assumed that the "baud rate" put a constraint on the data refresh rate but I wasn't sure how limiting 4800 was.
I tried my BU-353S4 (1Hz version) for the first time yesterday, with both an old Toshiba Thrive Android tablet and Win7 laptop, and the GPS performance was drastically better than the Thrive's internal GPS (but then again, my new LG GPad is also drastically better than the Thrive).
FWIW, I had not tried to use S&T in a long time, and I almost forgot how useful some of the features are, which are currently not available on any Android/iOS nav app. But I also forgot how clunky and cumbersome it is to do some basic things in S&T in comparison.
Since Street Atlas accepts 5Hz GPS data, maybe it's time to take another look at SA (despite the interface being even more complicated than S&T) for long trip planning, because there's NOTHING on Android or iOS that will do some of the things S&T and SA do. The Android app "Roadtrippers
" (a trip planning front end that hands off the actual nav to google maps/nav) shows what COULD be, but it's optimized for local trips (service, delivery, etc.) rather than long touring trips, and even the paid
version has some serious limitations that S&T never had (e.g.: max 500 waypoints routed per day... every time you recalculate a route, the total number of waypoints in the route is deducted from that limit).
