Trusted Reviews reviewed the Acer d150 Portable Navigator

As with other portable in-car sat-nav, the d150 is designed to work out of the box, However, it's certainly not as slick looking as its competitors. The housing is large, bulky and a frankly a bit ugly. The 3.5in, 320 x 240 resolution screen is surrounded by a seemingly oversized bezel, and the buttons on the fascia have a loose feel to them. In particular, the central joystick generally doesn't sit straight most of the time, which gives the whole thing a rather cheap feel to it.
