This GPS Receiver on USB is very efficient and extremely easy to use.
Install the driver, then a browser. (For me it's Microsoft motorways 2010)
connect the receiving antenna on a port USB.Repérer wearing install and open the browser.
It will search and find the receiver only get worse .At the install port if it is not the only one.
Everything works well and as quickly as my Tomtom XL IQ ... with the advantage of a screen up to 17 "for me.
What happiness for the co-driver!
