Infinity Sound system Eclipse Spyder 2003 how to tune even FM stations
 

Hello everyone,

My Eclipse spyder is imported from US and the tuner only change between odd numbers such 100,1 to 100.3 100.5 and so on. Is there any trick to change the increament or decreament to even like 100.2 100.4.
The sound system is a single CD with radio Infinity W287.

Thanks in advance
