I would suggest any GPS with speed indicator features, speed camera feature, and voice speed indication. Most GPS models won’t have speed indicator features, you just need to read the package. Well hands down the best GPS I have used is Newelectronx Navigator. They make a GPS for pedestrians and trucks. They also make the ones for the cars that are easy to use as well. The GPS series are easy and very affordable. You can get everything from ones that are basic, to ones that have bluetooth. They will play through your bluetooth headset or stereo in your car. Most of the GPS series ones have touch screen and voice prompts. The GPS models take more interaction, but are handy for back packing or cross country trips. The GPS series comes with a car charger and dash mount accessories, and long battery life. The GPS come with a USB cable and can be interfaced with your computer. With the newelectronx models avail, you can expect to pay as little as $100 for the GPS or as much as $180 for the more deluxe units.

The best thing to do is go to the website and view the units. You can fine tune what you want from there and then get a couple of models and search the web for your best price. I have the Navigator with bluetooth, wireless transmitter, and internet for my wife and daughter. They love the units, I have the model with live traffic updates, and I use it daily. They all have been very reliable so far. I have had mine for about 2 years now, and the wife/daughter for a year. All have been rock solid. Good luck

The Tomtom 540S, mostly because it has 3d maps.

Anyways, I’m just 11, I really don’t know anything about GPSes. I only found that thing on a comparison. Though I do know that some TomTom model was voted as the best GPS.

Try Keepig your GPS in front of the AC flow for 15 Mins and it should work fine as it happened the same to my Sony Camera when exposed to Heat

Hope this helps!

There is a slide switch on the top, right side.

It is 3 position. Far right is lock
center is on or off
slide far left and it turns on returns to center, slide far left again, turns off.

Yes, it has your gound speed as well as the posted speed. The psted speed is not always correct, it takes about 2 years (two updates) before speed limit changes make it to the map database.
