Yes, you can generally use a Roav Viva (or similar smart car charger) with an older car, provided your vehicle has a standard 12V cigarette lighter or accessory socket. The core requirement is a functional power source, not the car's age. However, the success of the experience largely depends on the specific condition of your older car's electrical system.
The primary consideration is the power output and stability of your car's 12V socket. Modern accessories like the Roav Viva require a stable power supply. In an older car, especially one with a worn alternator or a weak battery, voltage fluctuations can cause the device to malfunction, reset, or fail to charge properly. Using a simple multimeter to check that the socket provides a consistent voltage close to 12V-14V when the engine is running is a good preliminary step.
Beyond power, the main limitation involves features that rely on your car's built-in audio system. The Roav Viva typically connects via FM transmitter or an auxiliary (AUX) cable.
- FM Transmitter: This works with any car radio, old or new. You'll tune your car's radio to an unused FM frequency, and the Viva will broadcast to it. Audio quality can sometimes be affected by local radio station interference.
- AUX Cable: This provides superior sound quality but requires your older car to have a 3.5mm AUX input jack, which is uncommon in vehicles manufactured before the mid-2000s.
If your main goal is hands-free calling and basic voice commands, the Roav Viva is a great, low-cost way to add that functionality to an older vehicle. For navigation, it relies on your smartphone's data connection. Just be prepared for potential power issues and understand the audio connection limitations based on your specific car's equipment.
