iSimple Hands-Free Calling and Music Streaming Kit - Easy Bluetooth

In this review of the iSimple TranzIt BLU HF kit, the bottom line is clear: this is a practical, low-cost way to add reliable Bluetooth hands-free calling and music streaming to older vehicles that already have an FM radio or an aux input. The reviewer found the kit best for drivers who want a clean, behind-the-dash installation and a simple dash-mount button to control calls, music and voice recognition without replacing the factory head unit. Sound quality and call clarity are the single biggest reasons to consider this kit.

Key Features

• Bluetooth audio streaming: Streams music from an iPhone or Android phone directly to the vehicle sound system for playback of apps and stored music.
• Hands-free calling: Built-in hands-free calling supports call answering and voice recognition so drivers can keep their hands on the wheel.
• Dash-mount control button: A low-profile, dash-mountable button provides convenient play/pause, call control and quick access to phone voice functions without reaching for the phone.
• 3.5 mm audio output: A dedicated 3.5 mm audio output allows connection to a vehicle aux input for the best possible sound quality when an aux jack is available.
• FM antenna compatibility: Standard Motorola-style antenna connections enable installation into radios that accept a standard FM antenna, including some 12 V amplified antenna systems.

Who It's For

The iSimple kit is ideal for drivers with older cars who want modern Bluetooth streaming and hands-free calling without replacing the factory radio; it suits those comfortable with a behind-the-dash installation or willing to use a professional installer. It also fits owners who prefer a small, dedicated dash control rather than tapping a touchscreen or relying on a bulky adapter.

This is not the best choice for vehicles that lack any compatible antenna connector and cannot accept antenna adapters, or for users who want a full touchscreen head unit replacement with advanced navigation and display features. For purely plug-and-play dongles that only use FM modulation, users should compare alternatives if they lack an aux input and prioritize wireless FM convenience over audio fidelity.
