Navigation Receiver
How often do you update your Pioneer in-dash car receivers AVIC?

I'm looking at Pioneer AVIC-F700BT and receptors F90BT (Also the AVH-P3100DVD), but I wonder if the AVIC-F series will have a new model coming out soon. I searched Google, but could not find an answer. Does anyone know when your next model comes out? Do not want to buy one of these models only to discover that a new one is coming out in a month. Thanks in advance! Ps ... if anyone has any suggestions on a good double din receiver with both Bluetooth and iPod functions included, please let me know! (I do not need DVD or navigation, but may be a good option to have)

New units drive the leading manufacturers of audio are released during the next month or two. Pioneer AVIC rights of both future but as far as a release date goes, you're looking at about a year. Large retailers do not have a date AVIC shares in 2010.
