Hello, Volvo lover. I hope someone can help me solve my problem. I am a driver of a Volvo S80 built in 2003, but he belongs to the series from 2004 the built-in radio is a HU-601. To the sound system in the two front doors are tweeters. And in each of the four doors are again a speaker, in addition to two speakers in the hat rack. This radio I want to replace with a free-of-charge 2Din car radio which should be able to do the following. 1. Radio, 2 navigation, 3 Bluetooth, 4 video input for a rear camera with a display (Android) I do not yet realize what a device question comes up. I hope that someone of you has experiences with this topic, both devices and devices. For the new radio I would spend up to 750 euros. I hope someone can give me tips on my problem. Another question, can companies from which one buys the radio, also build this one on a Volvo S80, so that all that is running. Mfg Kurt
