I have a 2005 base TL and need to change my mice unit. ACURAOEMPARTS.com has two different part numbers, 38200-SEP-A04 and, 38200-SEP-A03, for the same part. Does any one know the difference besides the price? Heres the link: (both part numbers are for part number 4 in the diagram)
CONTROL UNIT (CABIN) for 2005 Acura TL SEDAN

 

That A04 replaced the A03, even if you order the A03 you should get the A04.
