i have an ovtavia a5 shape with the stream cd player unit which has burnt out, does anyone know if these can be replaced with other units or where the best place to get a new stream unit would be, cheers

You can get new ones of ebay, or you could look in the for sale section - enough people have upgraded RNS510s so there should be a few about.

Why not ask in the wanted section, or check the sales section. Someone was selling one recently.

I have a spare Stream unit with code that I could be convinced to part with,
