Been using it for a couple of weeks now, & am quite impressed with it.
Although lacking the screen size of my TomTom2 PDA setup, it will be replacing it due to its -put-in-the-pocket size & convenience.
The volume isnt as loud as the PDA, but is perfectly adequete even over the Harmon Kardon
Its been programmed to give warnings about upcoming Speed Cameras, as well as all the usual useful POI info such as Petrol stations & Carparks.
It only bad point against the PDA is lack of TouchScreen, as I now have to press a combination of buttons to navigate while on the move.
Of course, Being a Windows Smartphone ..it has been known to crash occaisionally but soon reboots back to working
Taking a few points from "Brassd" installation above, I have mounted the receiver under the parcel shelf where it is secured with Velcro for easy release, & is powered by the Boots Lighter socket when the ignition is on.
At the moment, I am switching it on by pressing the button through the grill with a Plastic tie end that sits nicely in the grill, but would welcome any mods to the circuitry as to switching it on whenever the external power is supplied ... Any Takers
