So, about the battery life and charging on the Rand McNally TND 750—our research shows it’s not all sunshine and rainbows.
Imagine you're on a long trip, and just like that, the battery starts draining even when it’s plugged in! Some folks mentioned it loses charge pretty fast, sometimes in just a few hours, which isn't ideal if you’re relying on it for navigation without any breaks.
On top of that, there have been reports about it occasionally dropping the GPS signal. Picture this: you're navigating smoothly, and suddenly, you’re booted back to the home screen. Not only is this annoying, but it also forces you to stop and reset everything, which isn’t the safest thing to do while driving.
That being said, the TND 750 does have a nice big 7-inch display with great visuals—so it's not all bad. It's just that the battery and signal issues can be a dealbreaker, especially if you need something super reliable for long drives.
Some people even suggest looking into alternatives, like options from Garmin, if reliability is a major concern for you.
In the end, it comes down to what you prioritize. If you can live with the quirks and you're a fan of the visual setup, the TND 750 could work for you.
But if having a consistent, hassle-free experience is non-negotiable, checking out other options might be a good move.
