MSSS problems on Eunos Mk1

Hi,

I’ve recently picked up this car and the MSSS only shows the clock. It bleeps when holding down the power button, but other than briefly responding with a CD (the surround speaker panel lit up) it went on to do nothing.

I’m anything but an expert, but after reviewing forums, can confirm that the interior footwell lights and cigarette lighter work ok.  The aerial is stuck, although this may be unrelated.

I’ve not removed the radio or checked the power/earth.

Be great to get some advice so I can decide whether to DIY or take it to a garage.

Thanks,

Steven

If this is the original radio that came with the car from Japan then it might not work in the UK. I couldn’t get mine to work and ditched it for a radio that works in the UK. As far as the Ariel goes it is probably only a burnt out fuse, that is one among a few, on the inside panel of the car below the steering wheel, under the dashboard somewhere. I say somewhere because an electrician did it for me, it took about 2 minutes to do.

The factory aerial rarely blows a fuse; the most frequent cause of faiure is a broken plastic track. New aerial mast required:

The MSSS was a Pioneer built unit on upgraded models, incorporating bass thumpers into the seats.

The MSSS unit was offered in the US, and there are a lot more experts on Miataforum, than here, in particular, Jeff Anderson. If the unit can be made serviceable, the radio can pick up UK stations merely by using a ,ow cost FM expander. A Norwegian contributor to the forum mentioned he was able to get into the electronics, to correct the display as well.

Thanks both. I should have been more specific - if I can get the CD to work then I’m quite happy. Less bothered about the radio.

There were a few different versions:

Like the factory cd-cassette, the two units are connected by an old fashioned DIN lead; this might be loose, disconnected, or just needs reseating. I suspect if the amp isn’t connected properly, nothing will work.

To remove the radio for examination, the critical element is to remove the central eyeballs, to get to 2 screws (the rest is pretty, I hope, self evident). The radio surround can be removed, leaving the radio, which is screwed into a chassis, in place.

Brilliant - thank you. I have the MSSS1. I’ll give it a go.

Nothing lost taking it out. If it needs repair, I doubt any audio specialist will be able to fix it economically. And, if need be, a new radio is very simple to fit.
