Hi, I have an AVIC-HD3 and was hoping to upgrade the maps on it as they are well out of date. Is there any way to upgrade even just the maps on this? or even get it to use the later model mapping as i believe the only DVD released by Pioneer to upgrade the maps was for 2008 and thats probably not going to have half of the new roads and bypasses in my area on them so not worth the $349AUD they retail for from their site. Cheers, Nik
