Halfords continues to extend its product range for integrating iPods into car audio systems.

This is part of a future-focused approach from the UK high street retailer. Recent analysis from Telematics Research Group (TRG), claims that by 2011 28 million cars in the US and 73 million cars worldwide will be equipped with iPod integration solutions of one kind or another.

Halfords has now added the newly-launched Sony CDX-GT300 Si to its available range. This head unit costs £199.99 and ships with an iPod-compatible lead.

Features include seven preset tone curves for a quick sound adjustment, or to tweak and digitally enhanced sound (a 24-bit digital to analogue converter). The system offers built-in processing for compressed digital music files and a front panel auxiliary input for the iPod. Two sets of preamp outputs (rear outputs switchable to subwoofer mode), subwoofer controls, and an AM/FM tuner complete the system, which can drive up to four 50 Watt speakers.
