ok i have the auto model MDX-C800REC it plays my car radio nicely, but i cant get my MD's to play. instructions dont say anything about it of course. So i call Sony's 1-800 number, get a tech helper, ask her Why it wont work, and she says maybe its a shotty disk, i dont have others to test out anyway. ok fine i now got myself a new walkman HI-MD player MZ-NH6000 slap some songs on it from my comp, toss the new disk into my car MD player. STILL DONT WORK ok fine, call sony up again, they spend a good 15 minutes asking each other about it, they say this car model can in fact play HI-MD's ok, but why wont my walkmans's disks play in there then? the box for my car deck says it can record off the radio, cool but does that mean thats ALL it can do? help me i need to play HI-MD's in my car, but i have a shotty deck or something, or im missing something simple, that wouldnt surprize me either.
