I bought this radio to ipod while having my in the car can, and so I do not carry around hundreds of CDs for my kids (for the fit perfectly on the iPod). The installation of the radio thanks to ISO shaft is easily feasible, only the repositioning of "plus" and "permanent positive" had to be done (the provided cable adapter, the two plug exchange of red and yellow), so that all settings are retained after switching off the ignition , For instructions, is unfortunately a bit poor ... The settings on the radio itself carried out largely intuitive, the manual is rarely needed. The sound is good, definitely better than my previous factory installed radio. The performance is sufficient for normal listeners, but miracles do not expect (4x26Watt are just not the world, but who needs powerful bass, which then buys another radio ...). The use of the front panel AUX input is simple and practical (you should adjust the AUX level, it is a bit quiet preset).
