Support Thread for the TND 500, TND 700 or future Rand McNally products. (part two)

These particular instances were not marked at all, most were the overarching buildings that are built over the interstate.

I am familiar with the snow height debacle & on all those that are snow height I have seen so far, they are marked on a white sign whereas the 'actual' height signs are marked on yellow like most other states.
The low warnings I encountered on 678 were not marked with either that I could see.

 

Hey Mark!

This is probably a map issue, but my 730 had a nervous breakdown when I continued west on TN840 west of I65, south of Nashville

On my 730, it doesn't know 840 exists past I65. Should that be updated by now? I think that section has been open a while.

Well if you can believe it I finally ran across some viaducts. Working out in the western suburbs of Chicago there are viaducts but they are spread out. Anyway I snapped a screenshot and as you can see it gives warnings on your route. It also gives you a warning when no route is set and your just using it in map mode. 3 types of warnings. There is a visual icon on the map (I used a red dot). There is a warning on the bottom of the screen just like all other alerts and there is a verbal speech warning as well. Just some FYI I suggest you rename the files shorten the name to just the number height. I just uploaded all the POI's with their original names "ROUTE-1 (USA) 13' 6 HEIGHT LIMIT" When the verbal warning is spoken it reads the full file name and that is not needed. Not to mention it pronounces USA as "U-sa" LOL. When I get around to it I will rename all the POI's like this one will be "13' 6 HEIGHT LIMIT".

How it works is there is a POI file for each inch of height. 12 files for each foot. From down to 11 feet (i think) up to over 15 feet. You can install all of them and be alerted to every viaduct or just the ones that you need to watch out for. Say if you have a 13' trailer you might install every file up to 13'0" or I would go couple inches higher just to be safe. There is really no need for you to get alerts for higher ones. This is good if you have the same trailer everyday.



Just a reminder that this is not from POI factory. Not free either. I bought the lifetime free update subscription from http://www.lowclearances.com/ Works with most GPS brands.

I realize that the TND's route you around any low viaducts but I just like seeing the numbers on the screen. Keeps me alert and aware of my surroundings.
