Looks like Pioneer is on the verge of announcing a followup to their AVIC-S1
GPS receiver smartly dubbed, the AVIC-S2. In fact, it would appear that they went so far as to inadvertently publish the specs on their web site before pulling the page. No prob, that's what Google's cache is for. From what we can tell, the S2 builds upon the S1's 3.5-inch touchscreen, SiRF Star III GPS, Bluetooth, SD slot, and 2GB of on-board memory by introducing an MP3 player and optional TMC
traffic receiver. Click the read link to check the cached data, while you can. Otherwise, we'll likely be checking this out up-close and hands-on at a CeBIT launch.
