There are a few radios I could recommend but only if you get the non euro versions with RCA line inputs. Sticking with Hitachi, the TRK -8080 US version has a proper line in, good sounding tuner and deck.
I know there are 5 Din units out there that can work as a usable line in but none that I’ve come across. (In Australia). I’ve even seen a euro M90 that has no useable line in (except the phono in via an attenuator). When I say ‘usable’, I mean a line in that requires no involvement what so ever with the tape deck.
Also keep an eye out for the early AIWA TPR series units that, despite not having a switch for line in, actually do have usable RCA inputs in the rear that function as a line in on tuner mode (the tuner is muted in favour of the RCA input signal).
