I've searched high and low but cannot determine what the difference is between the OEM head units 39100-SEP-A410 or 39100-SEP-A411. I know that they are both meant to work with navs (the non-navi head units are A100 or A010), but which one?

Also, does the faceplate ID matter at all (the little four letter code on the door of the cassette deck?

Thanks!

 

I refuse to believe that no one knows the answer to this!

 

Call an Acura dealer maybe?

 

as long as it is the same year tl radio with nav it will work. mine is an 04 and i bought one from another 04 tl with nav. part numbers were not identical just same year with nav matters. i was in the same boat as you took me 5 dealerships and countless calls to get a real anwser

 

I would match the face plate. I replace 1TB0 with a different part number, but it was still a 1TB0. I don't know about your particular case. Sorry.

 

fresh off the website at my work


39100-SEP-A41ZA TUNER ASSY. *NH525L* (PANASONIC)(GUN METALLIC) (FOR WARRANTY REPAIR REFER TO S/B 06-001) (FOR WARRANTY REPAIR, REFER TO S/B 06-001)

 

So I spoke to a very knowledgeable individual from a reputable eBay seller and he told me that the way Honda lists their parts, they would list it as 39100-SEP-A41x, because the last number isn't a big deal and usually just signifies a subsequent manufacturing run (of the same product). Just need to match the Faceplate ID and we're golden!

 

I replaced the 39100-SEP-A410 with 39100-SEP-A411 in my 05 Navi. Its been working perfectly for about 2 weeks now.
