Does anyone know of an after market command unit to fit my 2005 SL 500? Sat not working and screen is getting dark.

 

Hello and welcome to the forum! I would suggest checking out Crutchfield's site, link below. They have a very convenient searcher where you plug in your car's details and the populated results are only those that will fit your specific model. Hope this helps a bit.
