Talking to your gadgets is the first sign of madness, but people who insist on doing it should look at Pioneer's AVIC-F systems. The three models, the AVIC-F700BT, AVIC-F900BT and the AVIC F90BT all have a type of voice control developed by Pioneer alongside VoiceBox Technologies, which filters out the "um" and "ah" in everyday conversations to decipher your commands.

All three models have iPod connectivity, Bluetooth, MSN Direct, DH radio, XM and SIRIUS Satellite radio, CD and DVD-playback, as well as the advanced conversational voice recognition system. There's a 5.8-inch hi-resolution touch panel display, USB interface and SD card slot, plus maps from Tele Atlas of the US, Canada, Alaska and Hawaii. Available in June, the three models will cost $850, $1,100 and $1,200, respectively. [ecoustics.com]
