Mark,
Also, note that you have to install the driver for each USB port individually. If you swap USB ports, then you have to install the drivers for the new port.
Hi Allocator, if I changed USB port can you tell me how I'd install the drivers for the new port.
PS...Welcome QF1. I also use Vista but I installed the CD softward first and then the USB/Hardware. Agree with you that the CD cover tells you to install Hardware first then software, whereas anyone on here will tell you to do Software first. This seems a basic issue and should be correctly printed on the CD cover in the first place.
When you plug the USB lead into a different USB port and you get the "Found New Hardware" message, follow the prompts to install the driver, but select the Choose Location (or similar, can't remember of the top of my head) and browse to the /AirNav RadarBox 2009/Drivers directory. This installs the RB drivers rather that some random Windows/Internet driver.
This is the same for any USB device, be it a scanner, camera or RB - at least it is with XP and I presume it's the same with Vista.
