Well, my review of the Rand Mcnally TND 740 began yesterday evening, and ended this afternoon.
Stopped in at Dow Chemical in Freeport this morning to make my delivery. Go inside to watch the safety video because my card expired a few years ago. Come back about an hour later, and the unit is no longer on the map screen (just like the previous night). This time, it is on some dark screen that has options for updates, GPS repair, and something else. I click the x to get out of that screen, and nothing. Click it again, and the whole screen flickers, third time, it actually left that screen.
Get unloaded, go to leave and set my destination for Fort Smith, AR. It decides to save me a few miles and route me straight through the woods, through an area that flat out sucks to drive through. I figured this would be a good opportunity to see how it recalculates a new route when I ignore this one's desire to send me over to 59. I reach Houston and turn up 45. GPS is freaking out, tries to put me on 10 to get me over to 59. I ignore it, and continue up 45. it then tries to get me onto 610 to take me over to 59. Ignore it and continue on, it tries to put me on the beltway to get me over there. Still ignore it, and it tries to start u-turning me at exits.
Continue on further, and it has me exiting about 20 miles up the road to cut across over to 59. Ignore that, and a few other options, and by the time I am in Huntsville, it tries to send me across highway 19. I'm laughing at this point as I take Exit 118 and swing into the Peelot. From the Peelot, it wants be to go back down to highway 19 to get back over to 59, lol. Take GPS from window, put it back in the box, grab receipt, and into the store I go.
Hand the box and receipt to the clerk, and exchange it for the Garmin DEZL 580. Thought about the 770, but after putting the RM 7 inch screen up in my windshield, decided to just stick with a 5 inch screen.
Unbox, plug it in, and low and behold, it picks the correct route. I get to the Dallas area, and low and behold, it doesn't have the speed limits all screwed up.
Call me crazy, but I bet if I get on the Dallas North Tollway now, this GPS won't try to drag me into residential areas because it thinks there is a low bridge on the tollway.
One last thing, the Garmin with the little 5 inch screen is easier to view than that 7 inch RM was.
Looking to buy an antique map made of paper? Rand McNally is the place to go. Looking to buy an actual quality GPS? Go with Garmin, the people who know how to actually build a quality GPS.
