RCD300 upgrade?

[REX]

Hey! Just bought my first VW Passat the other day (my 2nd car overall actually), 2.0 litre diesel late 2007 model.

Now, I play almost all my music through my phone, most recently through bluetooth, when I'm on the move, and the basic radio unit that comes with these cars (rcd 300 I think) doesn't support any kind of music playing other than radio listening and cd's.

What's the most sensible move for me here? Buy some aux-in extension to plug with my current unit or buy a new chinese unit from aliexpress, ebay, etc.? Because the newer versions of the VW units like rns 510 are going for around 1000$ i think, wich is way too much for me.

I like these 7-8 inch units that seem to be able to fit but I'm just concerned about reliability and just general functuanality haha.

Please share your experience if you bought one of these chinese ones? Thx
