I installed a remote start system including transpoder bypass on my Lexus. Everything works fine except that the heater (digital) resets to 75 when I remote start. If I start with a key it goes to what I had previously used it at. Did I do something wrong? This was a complicated system and I am wondering what I could have missed.

Yea double check those wires..you are a brave soul to do a remote start on that vehicle. A mess up could set your bank account back pretty far.

It wasn't that bad, just went one step at a time. More time consuming then most that I have done. It is just weird because the heater will work but it just has not memory when the remote start is used. I wonder if there could be another ignition wire I missed. I will take another look.

Anyone else have any experience with the phenom?
