Question: Could you use it to measure the distance you have walked?
Document: If you just got your shiny new iPad or are a bit under impressed with the TomTom car adapter this is for you. This unit is deceptively small and uses your Bluetooth connection to connect to your phone. The battery lasts for 10+ hours of continuous signal acquisition. It is able to see it's position in 3D space so with the arm strap you could use it for geocaching or to capture signal for your sports apps that track your position for speed and distance.
The only complaint that I could possibly think of is that it would be nice if it could be a little more of a stand-alone GPS, with lat/long waypoints, time-distance calculations, etc., but I don't think that's what it was intended to do. A sticky pad mount like Dual's would be a nice option in addition to their lanyard.
Where is the on/ off switch. Who do you think you are Bill Gates??? ?Once charging it often reconnects and then discharges before you want to use it. (overnight)The really super silicone car mount has no gap for the mini usb connector. Those of us that drive long distance will need it connected.
I bought this so that I could use a number of mapping apps on my wifi only IPad 2. It works exactly as advertised and does a very nice job with my wifi only IPad 2. I highly recommend it.
Bought this for use with an Ipad4 running Navigon software, and could not be happier. This is a very precise and quick reacting unit. Current speed, location, and elevation signals from this unit are incredibly accurate at a very reasonable price.
This device works well. It locks onto signals pretty quickly, and seems to be accurate. I use it with both my Android and IOS devices. The only negative remark I could make would be that it appears to have a slight power drain even when turned off. If left turned off and to itself for several weeks, it requires several hours charging to reach a green light status.
Attempted to use this device this weekend for the first time. I could not get the unit to connect to my I-Pad or I-Phone. I contacted customer support and they advised to return the unit for exchange. The tech believes there is an issue with the device selection switch. I called back to returns to ask them for a RMA #. The person who answer the phone told me it was my responsibility to pay for the return postage.
Very pleased with the performance of this unit, it does everything it promises to do well. My non slip pad cracked shortly after delivery, called customer service and was mailed a replacement pad promptly. Could not have asked for better customer service. This unit works as advertised, it links with my iPad for multiple air navigation apps. I could not use my iPad built in GPS receiver in the cockpit of the DHC-8 airplane due to the windshield heating elements attenuating the GPS signals.
I regularly fly above that altitude. Specifications claim it works up to 59,000 feet. Not true!No customer support. I contacted them about the altitude problem two weeks ago but have not received a response. Zero STARS here!I over came the window interference by placing the unit by a window in the lavatory. Bluetooth works fine at that distance, about 15 feet.
will only feed GPS data to one device. Would be nice if iPhone and iPad could both get data simultaneously
Answer: Yes, we use in aviation and its very accurate!I saw some app to walk and you can conect this device.Good luck.
