The USA Spec BT35-HON is the broadest Honda Bluetooth retrofit on the market for 2003-2012 models, working with virtually every Nav and non-Nav factory radio in that range without disabling CD changers, rear-seat entertainment, or factory satellite radio. Choose it if you want a true plug-and-play upgrade that leaves every other factory feature untouched — just note it can't run alongside factory Bluetooth phone pairing at the same time.

Quick facts: BT35-HON · Compatible with select Honda Accord, Civic, Crosstour, CR-V, CR-Z, Element (EX/SX/SC), Fit, Insight, Odyssey, Pilot, Ridgeline, S2000 (2003–2012) · Hands-free calling and A2DP streaming · In-dash and external CD changers, RSE, and SAT radio remain functional.
