I'm of the mindset of not bothering with it. I have three panel mounted GPS units in the airplane. I really don't need another. It's easy enough to just swipe chart to the right location when I need the chart and I don't need to actually look at a chart very often at that.

So, I was dissapointed when I saw the the GPS in the prime is a no-go, but it wasn't a deal breaker for me. That said, I put in for that new dongle... it's free afterall, may as well give it a try.

please post back after you receive the dongle and test it on your flights. i bet you will be surprised as to how well and accurate the dongle performs.

Yes the free GPS Extension Kit; this is what Asus calls in the packaging it does help the GPS. What the Kit does is it disables the built in GPS and uses the dongle GPS. Works good, I tested to see indoors. I have the C3OK serial TP and the GPS kind of works outside, but with the dongle, it finds your location within 30 seconds after the first time. I prefer not to have the dongle, but at least I can use it if I ever wanted to really use the GPS. I have my TP rooted, so I might try the GPS hack that has been really working. Here is a quick view of the dongle.

It came in today and while I haven't flight tested it yet I think I have to say color me not impressed.

When I first got the tablet with Honeycomb still on it, I could get and lock onto GPS with it sitting on my dining room table near a window with an accuracy of 90 something feet. Outside was a little better... maybe 40 feet or so but I have no doubt that if I was diving (or flying) that the lock would be lost but I never tested it.

When the tablet updated to ICS, I lost ALL GPS function. Never could see a satellite inside or outside even when left for hours under an open sky.

Well, with the dongle, my GPS now see satellites again... but not as good as I had with the native GPS and Honecome operating system. Sitting here on the same dinning room table near the same window, I mostly do not have lock. Occasionally it will grab a lock but the best I've seen is accruacy o 143'. The last lock I had was to 757'. Currently as I type, no lock. Outside after setting for a long time, I got a lock to 70 or so feet. As I walked around the yard, accuracy fluctuated between that 70' and 125' but was mostly between 90' and 125'.

I'll have a chance to test it in a small aluminum cockpit going 200mph tomorrow and see how it does... not expecting much.

Woops, sorry. Nevermind. It didn't occur to me that it might perform better after restarting the prime (since it's hardware and the software has been restarted several times since the last update).

In any case, it's actually impressive now. Inside it's a solid 40 or so on the accuracy. Outside walking around the back yard, it holds a solid 12' or so. Best I've seen.

I'm feeling better about it's chances tomorrow. We'll see.

Finally got a chance to post back here. It worked flawlessly in the airplane. 17' to 20' accuracy when the Prime was sitting on the seat next to me. Would go to less than 10' accuracy when I held the Prime in front of me where it would normally be when I'm working on it and that's going at about 200mph. Nice feature added to the charting software.

I still regard it as just a 'nice feature' though. It really is easy enough to just swipe the chart to your location without GPS. Most airplanes have GPS in the panel now (mine has three) so you already know your location and most GPS units built in the last 12 years or so contain most of the information you'd need on a typical flight in the database so we don't even have to look at these charts during the actual flight that often anymore... and some of the more recent ones have the charts actually loaded into them (mine does not and is what I use the Prime for). When we douse a chart in flight, it's not to see where we are (since we already know that), it's to look up some detailed information that's not in our GPS databases, or perhaps the most common reason... to look up the spelling of an assigned intersection (spellings are typically very odd) so that we can access that intersection in the panel GPS.

Now, there are SOME older planes where the owners may not of updated their panels to have a GPS in them. For those, I'd want to buy a tablet with a good working GPS. In that case, a GPS would be a HUGE benefit.
