Question on a denso infotainment system, I have a l320 2011, and although I can't find any oe numbers to compare this with all info I got of pl24, are the D4 denso CD units the same as the l320of similar years, they look the same but can't see the oe numbers match, anyone from a LR specialist answer this or have any experience, ps I do understand I need it programed in, also does anyone know if mine can be repaired( its the oe one from the vehicle that use to work), it say on diag it wont programme to the vehicle.
