Auto-reverse is driving me bonkers!?

i have an '85 toyota corolla gts of which im very proud. I consider the car a real clic and i refuse to modify the interior as far as replacing the stereo deck and all. I have a philips cette adapter that i use with my '91 mercury topaz just fine but as far i know it doesnt have an auto-reverse feature in it. The adapter confuses my little toyota but has great quality for what little bits of music i catch before it switches sides. there doesnt seem to be a way to disable the auto reverse in the toyota either according to the manual, and ive even tried removing most of the gears in the cette itself (except the big center one...i was hoping this would reduce lag or tension or whatever would trigger the auto-reverse) to no avail. is there a brand known to byp the auto-reverse? ive been looking at Fm transmitters too but i have my doubts and wouldnt know where to start with them.... much thankies in advance! *^_^*
