Hi Guys, I am scanning the marketplace for a new single DIN head unit to form the basis of a complete system including Navigation, TV etc. I would also like the ability to have good control over an ipod, mp3 playback from DVD, and a decent touch screen interface for the whole lot. Ideally i'm after a 7" screen, but 6.5 would be ok. 5.1 surround isn't really a requirement at this stage. I have been looking at Alpine (IVAD310RB) and Pioneer (AVHP5700DVD) but note that Kenwood also have a large range of good looking units. I also considered the Pioneer AVIC X1R, but although it is supposed to be good in general, there are a lot of grumbles about it's iPOD support, and i'm not convinced about the ultimate flexibility of an all in one solution like this (although I may be wrong here). I know that Pioneer are shortly releasing a new range of AVIC head units, including one that is Bluetooth enabled (a very attractive feature). Can anybody recommend one particular unit? Is the Navigation system from any one brand supposed to be superior? Cheers.
