RT 44 Toyota in Raynham Mass installed a Toyota Brand Remote starter in my TCH. They charged $600 and they had and in-house Alarm guy do it so it wasn't farmed out.

They orginaly tried to put a 3rd party in but they had unsepcified installtion problems and had to order the Toyota one. Works great and integrates seemlessly with the Key Fob.

The car does warm up quick so I only need to start it a couple of minutes before leaving the house in order to Defrost the Windshield.
