I used an old 80's Goodmans radio cassette HU with aux in function with very good results on my classic .This gave me a period looking head unit with modern functionality .
The difficulty I experienced was that when playing off my phone the app used had a very small control panel when in play mode on screen .
This made selection and control almost impossible whilst driving resulting in me changing for a period looking Kenwood with USB facility .
Now the problem is similar in that track or album selection is very push buttony on pinheads
.... rendering change whilst driving virtually impossible again.
Deja vu
The new Kenwood is , surprisingly , not a country mile better than the Goodmans which is not a bad reflection on the Kenwood but more an accolade on the Goodmans so I am now looking for a better music app for my phone that retains a full screen control panel for < play/stop and > .
I've had a quick look on line but so far have not found anything but prior to looking deeper later thought I'd ask if any of you have encountered the same problem and if so what app are you using .
Thanks
Don
