This answer applies to R4i Mk2
R4i features Apples Universal Dock design which will accommodate all 30 pin iPod/iPhone models produced from 2004 to date. Each iPod/iPhone model requires a specific adaptor to guide and help support it when it is docked. Apple’s website explains more and shows which docking adapter should be used with each iPod/iPhone product. If you don’t have the correct adaptor these can be purchased from many Apple retailers and also directly from Apple through their website.
We also recommend that you use the Lightning Adapter Support (LAS) manufactured by Proporta.
30 pin iPod/iPhone models can be used in R4i without adapters, but care should be taken when inserting and removing. Connectors damaged through misuse are not covered by our two-year product guarantee.
