There may be a size war brewing among Android-based infotainment system builders. Ca-Fi thought it was sitting pretty with its 6.2-inch unit earlier this year, but we're starting to think it was rankled by similarly-sized devices like Parrot's Asteroid Smart -- that would help explain its upcoming, 7-inch Dashlinq. Along with one-upping a nemesis, the double-DIN system brings multitouch zoom to a heavily customized (if slightly creaky) Android 2.3 interface. Otherwise, we're looking at a familiar, if fairly sophisticated approach: there's a dedicated media DSP, GPS navigation, an SD card slot for local content and internet access through 3G or WiFi. Ca-Fi expects the Dashlinq to arrive in January for €499 ($657), at which point we hope there's at least a momentary truce in the battle for the car's center stack.
