I have an 09 LS460 and the radio, AM and FM only, stops working about 5 minutes after you turn them on but the satellite stations work fine. Any ideas?

 

Sat tuner is external u may have a bad tuner section in the radio...does cd, aux function properly? Repairing the tuner could get costly..cheap fix..use internet radio from your phone.. 2nd there is a guy on fleabay that claims to fix oem units.. email him for exact pricing
