USB GPS SatNav receiver/antenna for your Windows, Mac, or Linux laptop computer.
was first released in 2005. If I recall correctly, BU353 was among the very first two USB GPS receivers based on the very powerful SiRFstarIII chip. (The first one was MR-350). Four years later, and GlobalSat BU-353 is still doing very well. From what I read in various online communities, BU353 is by far the most popular laptop GPS receiver.
When it first released, it sold for over US$100.00. Now it can be purchased for under $38 in the USA or under £29 in Europe.
BU 353 comes with 60" (152 cm) of cable, which is in most cases a sufficient length to run it from your laptop to the dash board, close to the front window. You may need a USB extension cable if you wish to place it on the roof of your car. The base of BU-353 is magnetic so it can be attached to a vehicle's roof easily. The unit is waterproof, so rain or snow will not harm it.
BU-353 has software drivers available not just for Windows, but also for Mac and Linux. They are all on the included CD, and they can also be easily downloaded from the following GlobalSat web page: www.usglobalsat.com/p-62-bu-353-w.aspx
As of the time of this writing (October 10, 2009) Windows 7 has not been released yet, and GlobalSat website doesn't offer Win7 drivers. However, users have reported the Vista drivers work just fine with the 32 bit and even 64 bit versions of the Microsoft's new Windows 7 operating system.
