Suppport Thread for the TND 500, TND 700 or future Rand McNally products.

Mark, the light does go green. Still wont turn on, any suggestions?

 

I was on a run from Cleveland up into New Hampshire. The 720 routed me along I-90 / 86 / and 88. It was during the recent blizzard and I wasn't familiar if that way was more winding and hilly than 90 straight across; i also thought 90 might be better plowed. i kept having it recalculate (partly because my employer wants us to take 80 to avoid the tolls) but it always chose the 86/88 route. So when I came to the junction of 90/86 just outside of Erie, I stayed on 90. right at that point I checked the remaining mileage and on 86/88 it was 610. As soon as I passed the junction and it recalculated for 90, it said 585. So I'm wondering why it chose 86/88 in the first place. I know the internals are proprietary, but I'm curious because the only constraints I have are fastest route and freeways allow all. The only thing I can think of is that it considers there is more population along 90 and therefore more congestion making it slower. Any ideas? Thanks

 

Many thanks. I won't worry about it until after the first of the year, mail such as it is....I appreciate the input and the service!

 

Sorry, I wasn't very clear. I just pay the tolls myself as my primary interest is always the fastest route (total time, not necessarily mph). So I never had the intention of taking 80 (and understandably the 720 didn't route that way since I don't use "avoid tolls"). Everything worked out, I was just curious why it chose that way. Thanks.

 

This happens a LOT with my TND710 - Fastest not actually being the fastest.

As for not taking population or congestion into account without the traffic receiver, can you explain how this correlates to the advertised Key Navigation Features?

From the Rand web site:
TND710: Traffic Predictor: Integrates historic traffic patterns into routing (Available only on the TND 710)

I know that Ralph has the 720, but I'd expect that a later version would incorporate the features of the previous version, in this case the 710. You told me earlier that my TND710 did not have this feature, but the Rand web site says otherwise. Was this feature discontinued on the 720?
