2006 Radio issue

[oldcoach]

My DD has a 2006 Solara that right after having the oil changed she stated that the radio would not stay on the perset station. It would just change from like 105.2 to 105.3 or 105.4. She also stated that it was not the scan button, that if she pressed the scan button it acted like it should and found new station and would stay on it for the aloted time then find the next. But if she just trys a perset station it will stay for a little and then start changing. Anyone have this happen
