I have had this device for several years and it has worked flawlessly. Last night it would not respond to the key fob. Ther haven't been any battery problems or key fob problems. Fobs still lock & unlock the doors. It is also firmly connected to the OBD port. Any ideas on what may be wrong. I have not tried to reprogram yet.
What do you mean by "other non fob related functions"? The only thing that does not appear to be working are the functions related to the Top Down module.
The module allows you to do other things than just roll the windows up and down with the fob. For example, you can turn the radio on without the key in the ignition by pressing the reset button on the dash 3 times and then pressing button 3. You can also check last top speed recorded, set the speedo to read 40MPH all the time (like when you get busted speeding) and others.
I have only ever used it to put the windows up/down using the lock/unlock buttons on the fob and to unlock the doors when the gear selector was placed in park. I don't think that it unlocked the doors when I placed it in park.
