    QSTARZ BT-Q818X BT GPS Receiver

    Qstarz BT-Q818X Bluetooth GPS Receiver (66 ch MTKII, 42hrs, 5Hz Hardware Switch, Dual Interface USB/Bluetooth)

    66-Channel Performance tracking for fast acquisition and reacquisition Super high sensitivity -165dMb MTK II chipset Lower power consumption sup to 42hrs navigation time Less than 15 sec AGPS fix support Dual USB / Bluetooth 5Hz update rate, 3 level switch (5Hz-Nav-Off) for easy operation QZSS, DGPS(WAAS+EGNOS+MSAS) Support Auto On/Off function

    I decided to order this unit and havn't seen anything mentioned on MP3Car about it, but the price looks good and about the same as I paid for BU-353 4 years ago (that died last week)
    On this unit the 5Hz has a hardware switch, where-as on some MTK receivers you have to set it in software, which resets back to 1Hz when battery is drained, guess I'll have a new toy to play with next week.

    good news about it, you dont have to use bluetooth, you can use USB as well, some other 5Hz receivers have usb just for charging only, no data! no more turning the unit on with a button unlike other 5Hz receivers either, it will run till battery is dead, and the pc bootup usb will turn it back on while charging...
    it has AGPS which takes about 10 seconds to update via their software, and the almanac data lasts up to 7 days! it sees alot of sats from inside center of home too...

    good thing is no waiting for BT to sync to start using gps if we use usb
    sees 9 sats in middle of home...

    Canmore GT-750 FL is another good Bluetooth GPS Receiver

    Similar to bt-q818x but more friendly use.

    I got my BT-Q818X several weeks ago, too, and I love it. Things do change in the industry, but as of today (December 2009), if I had to buy another GPS for a PC, I would not hesitate to buy it again. It meets my needs. I love the long battery life. I love the fact that you can use it via USB or via Bluetooth.

    fix time is a joke, i use the USB to keep it direct to pc so it always charges at same time, and when carpc is off the gps is in standby, no need to FIX and i get signal inside garages. Ive tried it on blackberry bold and its fast, off and on hits less than 15 secs sync plus it can handle multiple bluetooth connections and usb data at same time without crashing... and i aint complaining about the 100$ price tag as the BU-353 GPS was same price 3 years ago and the signal and sync sucked big time... on top of it, no more cursor jumps from gps sitting at intersections or going downtown, MTK chipset wins..
