O2 XDA Guide satnav phone

All roads lead to roam

It's pretty good, as far as it goes, but unfortunately, the limited screen size – especially since you're stuck with portrait resolution – means that the keyboard is a little too cramped to use with ease when it's stuck to your windscreen. We'd have liked a little more volume to be available from the loudspeaker too, to hear it better over rush hour traffic.

The 3.2Mp camera works fine for snapshots, but video is disappointing

Speaking of travelling, the O2 XDA Guide comes with a quick-fit cradle and charger for your car. The charger plugs into your car's cigarette lighter, while the cradle attaches to your windscreen with a suction cup featuring a lever to activate the sucker. Certainly, a couple of quality steps up from lick it and stick it. While it doesn't beat a professionally fitted cradle, it gave us no cause for complaint during several days of use.

Cruising around the menus is made fun thanks to HTC's thumb-friendly TouchFLO interface, which means you'll rarely have to resort to the Windows Mobile 6.1 Professional operating system that lies behind it.

The 3.2Mp camera is quickly accessed from one of the programmable soft keys on the touch screen home page and takes about two seconds to launch. The image quality isn't bad, although colours could be a little more vibrant and edges could be slightly sharper and more defined. As a basic snapper though, it easily passes muster. Video quality slips a bit, with fast motion recordings prone to blurring and, consequently, not much use.

By contrast, viewing pictures is a joy thanks to HTC's viewing gallery, which seems to have mysteriously disappeared from some of recent Touch models. You can switch between pics by brushing your finger across the screen, and zoom in on a part of a pic by drawing a circle with your finger on the screen.

On the cards: up to 32GB on microSDHC storage is supported

The music player includes album cover art and a ten-band graphic equaliser. While the supplied headphones are on the tinny side, they at least come with (hooray!) an adaptor for the USB port, so you can upgrade them via 3.5mm headphone jack – not an option usually available on its Touch cousins.
