2015 Nissan Altima Sedan 2.5 SV 4dr Sedan (2.5L 4cyl CVT)
Poor Radio Reception
 If you buy a 2016 Altima SV with the Navigation package be aware that the radio has terrible, non-existent reception in the upper AM frequencies.  Nissan is aware of the problem and it affects ALL SV,s with the Navigation Radio, and they say that this is NORMAL for this car and they will not do anything about it. Nissan states that there is no other manufacturer for the radio that will fit into the SV and there  is NO fix for the problem.Update: July 7 2016.  Nissan is sending the Regional Tech Support  to meet with me next week to listen to the radio and determine if there is anything that can be done to fix it.
