We have exchange service too for £265 if your faulty unit is in good condition. This unit is in full working condition and comes with radio code so it’s perfect choice to just replace it with your faulty ones , if your unit just showed logo or just keep turn on and off then if good for you .Main problem with these units is radio code as can’t be decode by online service or even main Honda dealer but this unit has got code .There is 3 months warranty so you have enough time to check it properly.This unit fit on cars with external amplifier so if you are not sure just asked me before buying it .Thanks
