Question: Will this device work with the iphone 6 and ulmon maps in barcelona without wifi and cell service??
Document: I bought this item with the intent of using my iTouch as a pseudo iPhone when jogging and driving. Unfortunately, while the GPS functions well, many of the running and navigation apps also require internet connectivity to load maps and other data which sort of makes this product redundant. I even e-mailed customer service for Dual Electronics and they confirmed that most apps require internet connectivity. However, if you do your research first and cand find apps that will work 'off line' then the actual GPS functions very well.
Using it in conjunction with my wifi IPAD and the Motion X GPS app, I now have a large screen navigation device that displays topo, aerial, and road maps in a very portable package. Plus, I didn't have to get a 4g IPAD and a 4g service contract.Last week I tested the XGPS150 while on a trip over rough forest service roads. I doubted the little silicone holder it came with would secure the device to my dash.
I have a regular iPad and a Mini iPad and a iPhone 4 all 3G service, with foreflight on them. I cant tell any difference in the location accuracy with it off or with it on!.... Sure looks pretty when it is on and displayed on the iPad!....... Not sure I needed it with the 3G  from the cell towers!... Selby
Gotta rate the device highly, but the free gps maps all suck. Battery life could be better. but that is true for everything. It would be nice if it matched the iPad, but alas, no.If you try to use one of the free gps aps be sure to use one that downloads the maps. Your vehicle will not always be wifi connected so the others flat do not work reliably.
I am using my iPad with ForeFlight for aviation moving maps. The internal GPS in the iPad1 works pretty well, but it does drop out. I have read great reviews on this product. I was going to buy it from Sporty's Pilot Shop, but found it for 20% less on Amazon. And I got free shipping. So great price, great service. The device actually arrived next-day for the two-day shipping cost.
The battery lifetime was initially good, but in 6-8 months it had dropped to 30% of the advertised time. GPS performance was fine, but without a replaceable battery, it's just a paperweight.
Got this to work with my iPhone 4 and iPad during flights in out aircraft. We use both Foreflight and WingX 7 Pro and this unit works with both of them. Acquires quickly and Bluetooth connection is solid. Free app for iOS devices could be a little cleaner but device itself is great. N3723W
I bought this to give GPS capability to my iPad sailing apps as I go offshore. I could see the GPS was working, but it would place me on my charts. When I am in port, with just 2G network, this device would not work with FB or Google maps locations. Very disappointed. This device did not work as advertise.
Copilot live HD... the best of the bunch so far.. have use for trips from CT to PA and NC without hiccup. offline maps & routing, but if you have a hotspot, it also has bing local search within the app which is handy for finding a starbuck enroute..edited: 2/21/12 to update apps based on comments (and thankx to the contributors)
It detected satellites quickly and routinely acquired seven satellites without even breaking a sweat. I laid the remote unit on my window sill when I first took it out of the box, and it showed my exact position (with my iPad's Wi-Fi turned off) in less than a minute. It worked perfectly with Google Maps, MotionX GPS and the Navionics Marine app. The built-in battery charges quickly and maintains it's charge.
Answer: It will work on an iPhone 6 via Bluetooth. You will need to turn off the cellular portion of the phone so that there is no cross information between the phone and the XGPS150A receiver. Turning off the cellular portion of the phone will also save your phone battery
