Mini Review: Bluetooth GPS Qstarz BT-Q890
Okay, after long time researching, I decided to buy this one. Qstartz BT-Q890.
Amazon link. Jonathan's review did it for me in the end - check it out. Manufacturer link here.
So it has the MTK chipset, 66ch, super high sensitivity, 5Hz refresh rate, small, etc. What matters for me in the end is that it works very well. I leave it inside my center console, and it picks up signal better and faster than my old 5Hz Garmin GPS 18 mounted outside the car!

• Super high sensitivity -165dBm adopting the latest MTK II chipset

• One touch switch to 5Hz update rate for higher accuracy of the demand of eXtreme Sport

There's also this: it works as a bluetooth gps AND a usb gps. Each one on its own com port, if you so wish. So right there you have two com ports with NMEA data for you.
Works great with Xport, provided there's an application opening the port, Xport turns the thing on. No reaching to it and pressing the on button, like some bluetooth units out there.
Also it does resume from hibernating with Windows 7. It also resumes from hybrid sleep too, very fast, no issues. I used to have BSODs with the Garmin (they do not update their drivers easily.)
The thing I like most with this bluetooth gps is that it requires no drivers to install, if you so wish. If your bluetooth stack is up and running, pair it, and it will work for you. Talk about future proof! As long as BT is out there, this is going to work (windows 8, 9, 10, etc.). I'm tired of downloading, updating drivers, trying to make XP drivers work with Vista, later Vista with win7, etc. This the end of it!
Now having said that, I later installed the USB drivers for this thing (otherwise when plugged it would just charge the thing via USB). They also work fine with windows 7 too, but as usual, not sure about XP, Vista, etc. Again, if your bluetooth drivers work, this thing should work with it.
Also it comes with some very cool applications, which displays sat info, lock, they can save track data, etc. Using the apps you can update almanac data and thus enable assisted GPS function for even faster operation.
Man, when I think about all the frustrating hours wiring and hiding and extending my usb cable for my external Garmin GPS 18...I even burned a usb hub in the process. Finally I've found what I need.
Now I'm going to investigate if I can use it with my J/B 3G iPhone (regular iPhone does not have a BT stack) and see if I can use more precise apps with it than Rev2.0 (and enjoy the 5Hz benefits of this unit.)
