i have it installed on my 8 for a couple months now. and it stopped working...ive noticed that the only time it works is when it is extremely cold in the car and once it heats up it stops working again. Has anyone else had this problem?

 

Replace it with Metra's ASWC. No programming required, automatically figures out the car and radio, and no key lag. I have one in my RX8 with a Pio radio.

 

Thanks for the info. I'm also using a pioneer radio
