Just come back from the weekly shop at Tesco Twickenham (Mogden Lane) and while I was there I saw the Sony CDXTGT410 reduced to £57.97 (+ club card points).
Cheapest elsewhere that I have seen is £79.99 Argos clearance (If you find stock).
The CDX-GT410 car radio is the most advanced sound system that you can get for your car, as it comes with a 4 x 50 W amplifier, a 30-preset RDS-EON tuner and a Drive-S CD player compatible with MP3, WMA, Atrac and AAC formats. It has a USB port in the front and 2 auxiliary audio inputs, and it's supplied with a remote control for even more user friendliness. The CDX-GT410 car radio combines style, sound quality and a number of extension possibilities, so you can enjoy hours of non-stop music on all your journeys.
