I recently ordered a dice kit for my honda accord w/navi and i got the i-honda-r3 and not the r-4. i need to find a place to exchange it for the one that supports the nav option. is there any one that knows a place near santa monica or around there? I know that there is a price differance and i'm willing to pay it.

Thanks!

 

hmm you should try it. my box was marked r3..
but the receipt says r4.. and it works..
