I paid $28.99 via Paypal to radio-code.come for the solution set for resetting the radio and security system in my Mazda RX-7. After several attempts per the instructions they provided, I could only go to step 6 of their 9 step proceedure. I have emailed Mr Riebman in efforts to correct the problem, but he not anyone at radio-code.com will respond. This is a ripoff!
