FAQ
TL;DR: Yes, you can retrofit the 2006 CR‑V II with the OEM Honda navi; you’ll add 1 extra connector cube. "You need to add one cube." [Elektroda, SZYMON BYDGOSZCZ, post #16756128]
Why it matters: This FAQ shows how to wire power and signals, and whether it’s worth doing for daily navigation.
- Retrofit is technically possible, but several forum experts call this factory navi "bad" and not worth it. [Elektroda, nici, post #16754075]
- You must add one extra connector “cube” to power the navi section. [Elektroda, SZYMON BYDGOSZCZ, post #16756128]
- That cube carries UB+ (battery), ACC (accessory), and engine‑run signals. [Elektroda, SZYMON BYDGOSZCZ, post #16774374]
- Speed (VSS) goes to the instrument cluster; reverse input location varies by car. [Elektroda, nici, post #16829610]
- Typical last map discs people find are circa 2008–2013, so coverage is dated. [Elektroda, recki-quadra, post #16754298]

Can I install the OEM Honda navigation into a 2006 CR‑V II?
Yes. Users confirmed the swap works, though several advise against it because the unit’s performance and maps are weak. One expert put it plainly: "This navi is bad ...." If you still proceed, focus on power and signal wiring details covered below. [Elektroda, nici, post #16754075]
Do I need an extra connector or adapter to power the navigation?
Yes. You add one extra connector cube to feed the navigation section. That addition enables the head unit to power up correctly after the retrofit. It’s the key hardware difference from the basic CD radio. "You need to add one cube." [Elektroda, SZYMON BYDGOSZCZ, post #16756128]
Which signals must that extra cube provide (UB+, ACC, engine-run)?
The cube carries three lines: UB+ (constant battery 12 V), ACC (accessory 12 V), and an engine‑running signal. These lines wake and keep the navigation section alive beyond simple ACC power. This matches how the factory-equipped units are wired. [Elektroda, SZYMON BYDGOSZCZ, post #16774374]
Where do I find the speed signal (VSS) and reverse signal near the radio?
Use the vehicle wiring diagram. The speed signal routes to the instrument cluster. The reverse input has no single standard location in this platform, so you may need to trace it. Plan a continuity test before final assembly. [Elektroda, nici, post #16829610]
Will the head unit power on after I add the cube and a GPS antenna?
Yes. After adding the connector and basic wiring, users reported the radio section powers and works. You can then address the remaining three wires and GPS to complete navigation features. Confirm grounds and fuses first. [Elektroda, pyzdra000, post #16827878]
Is it worth installing this OEM navi in 2025?
Most say no. Performance lags modern units, and maps are outdated or missing in key regions. As one expert summarized: "This navi is bad ...." Consider a modern double‑DIN with CarPlay/Android Auto instead. [Elektroda, nici, post #16754075]
Are current maps available for Poland on this model?
No. A pro notes there is no Poland map for this specific model line, making guidance a gimmick. This is the primary edge case/failure: hardware works, navigation usefulness doesn’t. [Elektroda, SZYMON BYDGOSZCZ, post #16831216]
How old are the map discs people actually find for this unit?
Expect old media. Users commonly encounter discs circa 2008–2013, which leaves many new roads missing. "The producer does not profit from updating old solutions" and updates stop. [Elektroda, recki-quadra, post #16754298]
What do the acronyms mean here (UB+, ACC, engine‑run)?
UB+ is constant battery 12 V. ACC is accessory-switched 12 V. Engine‑run is a line indicating the engine is running. These are the three signals called out for the added cube connector. [Elektroda, SZYMON BYDGOSZCZ, post #16774374]
Can I grab IGN/ACC power from the wide ISO plug behind the original radio?
Yes. A user confirmed measurable voltage on the wide ISO plug with the key turned. That feed can serve ACC/IGN for the retrofit, with proper fusing and routing. Verify with a meter before permanent connections. [Elektroda, pyzdra000, post #16829513]
How do I wire the retrofit in three steps?
- Add the extra cube and connect UB+, ACC, and the engine‑run signal.
- Install the GPS antenna and route it with clean ground and fused power.
- Tap the speed and reverse signals per the wiring diagram if you want full features. [Elektroda, SZYMON BYDGOSZCZ, post #16756128]
What if I skip wiring speed or reverse inputs?
The unit may still power and show the interface, but navigation accuracy and auto‑zoom on reverse can suffer. In Poland, missing map coverage makes the feature more of a display than a tool anyway. [Elektroda, SZYMON BYDGOSZCZ, post #16831216]
