    Just like Fusion-One, the only other GPS receiver I have experience with is the Deluo. I had the Deluo mounted near my rearview mirror right up against the windshield and was less than pleased with its performance. Acquisition seemed slow and once it found the satellites, the lock wasn't that great. On average, I would get a weak lock on 5-6 satellites and if I was lucky, 8-9. I moved it there because the receiver was previously located on the dashboard and had difficulty finding and locking onto satellites.

    With the AyAy, acquisition is comparable to the Deluo. It didn't seem to be any faster or slower than the Deluo. However, once it locked onto the satellites, that is another story. It would consistently find 12 satellites and lock onto 8-9 satellites with a strong lock. When I first got the receiver and did some testing, I placed it in various areas of my car (on the dash, in the glovebox, on the passenger seat, in the center console, etc.) while I was driving and it would find and lock onto 8-9 satellites. Also, in areas of dense foliage where the Deluo would lose the satellites, the AyAy had no problem maintaing the lock on the satellites.

    Overall, I definitely prefer the AyAy over the Deluo.

    I live in Montreal, and do plenty of city driving.. it performs well in canyons, I have no problem maintaining lock.. and have never seen it drop below 4 satelites, in the deepest parts of the city. When I pass under overpasses, if I'm going a good speed. the iguidance car icon doesn't even blink to red for that split second on me...

    Sxott, actually.. I learned that if you power the gps down, and then power it up again at a different location, it takes much longer to attain lock.. this is because it stores its last location data in the memory, and attempts to do a quick lock with this data.. if after a minute it can't do a quick connect, it goes through a standard coldlock, which can take another minute.. so if you relocate it, it can take up to 2 minutes to relock... I've never had any problem with mine, though.. and I always park inside a parking garage.. it gets lock before I'm 100 feet out of the garage door.

    I dunno what the differences are with sirf 2 and 3.. ayay claims to have a better sensitivity compared with some SIRF III units, so I dunno.. sirf3 is a different chipset compared with sirf2.. which definitly makes a difference, but antenna design and other stuff i dont know a thing about are to be taken into consideration as well. Maybe someone with a sirf3 could test the ayay to give us an idea of how it compares?

    One reason I think it does so well is that the antenna has a solid titanium baseplate (the entire casing) to make a groundplate.. but I could be wrong.

    At any rate, I'm very happy with my AyAy.

    What is the primary difference between the USB serial interface for GPS.

    As the promised update, yes it gets a signal quite quicky now. I am not sure exactly what the interefernce was from, I haven't yet checked if the CD player will interfere (as it is on top of the head unit hidden out of site), but when using the line in on the HU (which is all I really use) there is no intereference and it is very awesome. I have a WRX and the HU on the top, and the AyAy is so nice and slim it slipped right under the gauge pod, no one will no it is there, and if I take the faceplate hopefully no one will want the HU enough to find out it exists

    Just wanted to give an update on the AyAy after using it for a month.

    Similar to sxott, when I first started using the receiver, acquisition times seemed to be a bit slow. Now it seems to be much, much faster. When starting iGuidance, the receiver will lock onto 8-9 sats instantly (and even before the GPS Info window appears). However, coming out of hibernation, it takes a good 5-10 seconds to get a lock. I'm not sure what caused the slow acquisition times earlier, but it's much faster now.

    I'm also amazed at how sensitive the receiver is. It will maintain a lock when I pass under bridges and even while stopped at a red light under a bridge, the AyAy maintained a pretty strong lock on 5 satellites (and this is with the receiver in my glovebox).

    Like Fusion-One, I have no reservations recommending this unit.

    I just received mine and it is great!!! I have had DeLorme (non LT-20) and the Pharos branded as Microsoft mouse and this unit is better than both and the Ayay Sir gets along with hibernation unlike the Microsoft unit. I would highly recommend it and by the way I only paid $35.50 shipped so I think I got a good deal.

    Quick question, you can find these units on ebay for $24.99+$25shipping or $50. The offical site sells them for $120. Are the units being sold on ebay legitimate or knock-offs?

    I just picked one of these up. It is my first gps reciever, but i am very impressed. Heres the listing on ebay http://cgi.ebay.com/ws/eBayISAPI.dll...m=160036407558 . Its ttff on its first ever run was less than a minute, and was around 45 seconds the last time i tested it. That was in a wide open area. Currently, inside my house, within five feet of a standard sized window it has 6 sats locked. Driving in wooded areas with lots of tree coverage was also no problem. It was positioned on my center console, under my arm, in a car with all windows except the windshield tinted. I plan on taking a trip to Atlanta on the weekend of Nov 11th, where I plan to test out my whole software setup on my laptop through an fm modulator into my head unit. Ill edit this post on my experiences in the urban jungle with this unit.

    i just got one as well. have you noticed that the updating of position in the gps program is slow. or is that an effect of my pc (pIII 850mhz, 256mb ram)
