New radio – what is the current market?

Hello together, for a long time I had been able to pay attention to the topic of Carhifi with me or my car only in a subordinated way. But the virus is still in me and during the last rides in nice weather it packed me again: I need a new plant budget are in total so 2500.- Euro, which is why I probably also have the plant professionally installed. However, it is with me with dealers in the immediate vicinity rather thinly sown (who knows which in the room 63739 can also w This is why I want to start here with the base and this is the good radio. I had imagined such a frame 500-700 euros. From the performances it should be approximately comparable with my old radio, the Alpine 9815. I write my ideas together: – Operation of 2-way, better 3-way, system active plus sub must be possible, therefore corresponding crossovers – MP3 capability – optically it should fit into a Peugeot 307 (illumination). I have attached a picture of the interior. Alternatively, I can also imagine the solution that you can operate it via the original radio, if it is somehow price comparable possible. The radio has to stay in anyway, because some functions of the on-board computer are controlled via the radio, so it has to remain connected to the bus system of the car. I am grateful about many suggestions, what there is currently so on the market. I would like already a N eugert, maximally a young used one, which then has to be in very good condition. Thanks for your cooperation Greeting Tecci
