What is the best GPS Hardware Unit for a laptop
Marvin Hlavac
Terry mentioned Qstarz BT-Q818X, and if I had to make a purchase decision today, I would likely very seriously consider it. Qstarz BT-Q818X is based on the MTK2 chipset, which means it has a very good sensitivity to weak satellite signals. It is rated for 42 hours of battery life. And what I personally like about this unit is that you can connect it to your laptop via Bluetooth or via USB(!). This is excellent if you are not 100% certain if you will be using it as a Bluetooth or a USB unit.

Two warnings:

1. If you wish to use it with Microsoft Streets and Trips, use the included utility software to change the refresh rate of the unit from 5Hz down to 1Hz. If you don't, you will notice big lag in you GPS position in Streets & Trips.

2. Baud rate of the Qstarz BT-Q818X receiver is I believe much higher than 4,800. This should not be an issue with Streets & Trips as long as you use the Bluetooth connection. However, if you wish to use Streets & Trips with a USB GPS receiver with baud rate higher than 4,800 you will need utility software GpsGate (or another free alternative).

Thanks Marvin you and other have been a great help.
I just bought the Q-1000X: Qstarz BT-Q1000X Bluetooth Data Logger GPS Receiver (66 ch, 1-5Hz Update Rate, AGPS.

Hope this unit is up to the the unit you mentioned.

Thanks again.

Dave, I think that's an excellent choice. I think the Qstarz BT-Q1000X and Qstarz BT-Q818X are identical units, with the only difference being that the Q1000X has also a data-logging capability in addition to being a GPS receiver (Bluetooth and USB).

Let us know how you like it, when you have had a time to play with it for a while.
