After two days test my new toy BT-Q890(5Hz) i happy with it compare i use b4 SIRFStarIII chipset.

Only when i switch to 5Hz mode, the battery will run out very fast(3-4 hours). Normal mode 1Hz will up to 12 hours. So have to use car charger to charge it when i use in 5Hz mode.

Is it not possible to let it run on the car's voltage while on the road??? Which then allows you packed with a full power load whenever you leave the car? I'm going to ask this from local dealer, I was informed, the RRP for our country on that, click>> 66-ch Qstarz BT-Q1300 model is going at about €115 incl. 19% tax excl. delivery.

I was further informed, my TomTom won't work on this due to its built-in antenna, and I can't switch it out either to utilize the BT function that the Qstarz supports as an alternative source. While my Nuvi, which is w/o BT, cannot work either when I close the antenna flap and the optional usb port is the mini type.

The usb cable that comes with the 12v charger, is with one that has a mini usb on one end and the other is the standard usb.

So thats no good either. He recommends to have the unit plugged to car power source when traveling so one will have full supply from charged battery outside the car when needed.

If my Nuvi has a BT, it would serve awesomely well for reception is being enhanced through this alternative. Hmmm, I may need BT then on the next unit for such purposes. :rock:

I posted those same comments as above in the Forum of the Buy GPS shop that supplied the said range of the Qstarz and this was promptly recieved from a response to my submitted thread.
See what you make out of it.

Hi. You cannot use any of our Bluetooth GPS receiver on either of your Personal Navigation Devices (TomTom 910 and Garmin Nuvi) because they both do NOT Support Bluetooth with Serial Port Profile (SPP protocol).

I recommend you purchase antenna booster antenna for both units to improve the GPS reception.
:rolleyes: :shock:

Hallo adrianyujs,

You know apparently not the difference between the several chipsets off MTK and Transystem Inc. :-k Please you should learn the difference between the serval MTK chipset and the serval MTK based devices. :D Notice, the QStarz Nano use a MT3329 GPS Receiver chip and the older models use a 3318 chip.

Please, point me a SiRF-Chip with 5Hz samplingrate. :evil:

You can use a external USB power pack to recharge the Nano device.

I have both GPS units and I had "flown" then off against one another for quite a while and I am still unable to form a definitive conclusion. If any, the MTK seems to be slightly quicker with TTFF than the SiRF Star III on more occasions than the SiRF Star III did against the MTK.

As for the MTK running in 5 Hz it is definitely much more superior to the SiRf Star III at 1 Hz when it comes to instant speed display and accuracy as the resolution is much, much better at 5 Hz. Of course my 10 Hz Performacebox is even more superior in this respect. I am making these statements based on first hand trials not hearsays but I still love both of them as the apart from speed display and track logs, I find it difficult to conclude that one is better than the other when used as a navigation device.
Since the first day I know about MTK chipset I never want to have SiRF Star III for my GPSr. [-X
