Medion's new GoPal GPS units have an unusual extra feature intended as a deterrant for thieves: fingerprint scanners. The GoPal X5535, P5235 and P5435 all have a tiny scanner and will only work when they recognize one of five stored prints, making them useless if stolen. They've all got 5-inch screens, though the P5235 has voice control, the P5435 has Bluetooth and the X5535 has a gyrometer so it can compensate for brief losses of GPS signal by detecting car movements—all three get live traffic updates with Traffic Message Channel. Pretty neat, though leaving your GPS in your car is likely to tempt some thieves to break in, no matter how secure the device itself is. Out in Europe at the moment, no pricing info is available.
