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

I had the same problem yesterday around noon myself. I was in Garland and taking I 635 over the 35E. I though maybe because I removed it from the dash and mounted it down on the dash panel. As I traveled farther North toward OKCTY, it began tracking normally. I'm thinking now it may have been a glitch in the satellite system and not with my TND-720.

 

Cutout a piece of cardboard to make a sunshade. Make it a wrap around design so you can tape it together then just slip it over the unit when needed or slip it off when not.

 

I put my baseball cap on it!! and sometimes at night- right over it!

 

No glitch on my garmin dezl 560 that is sitting right beside it on the dash and yea it was probably about 10 am if I had my computer up I could probably zoom in on the pics I posted and see the local time

 

Time shows 1037 Denver time

 

I know that when I was in the broadcasting field, twice yearly we would deal with lots of noise on the satellite feeds due to sun spots. But this was the wrong time of year for that, so I figured it was something simple. 720 has been perfect since then.

 

It was a problem with 720 so this is the correct place to post what I did
