I have posted before that the speaker and chimes only work at a certain temp in the cabin. Has moved up past 90 now to work after steady progression over several years. Dont care about radio as much as the chimes. use the cellphone for radio when I want it. I already tried replacing the amp with no difference made. I have power to the radio head and have checked fuses. I know this is not a unique situation to my vehicle as have read that others had the problem but never saw one that said they fixed it. If the security aspect were not involved, I would just swap to a replacement used radio. Has anyone with a 2000-2006 had this issue and fixed it and how did you do it. Thanks.
