everytime I switch it on I have to go through the set up stage, language, and time... ect. I it won't save it!! any help pleass

Pull the stereo out, and disconnect the yellow and red wires using their mid-wire connectors near the end of the wire loom, connect the red to yellow and vice versa. This should stop happening then.

I already have a microphone installed neatly into my car. The microphone has a 2.5 mm jack. Will it connect into this unit?

Well yes it has a standard microphone jack at the back .

I preset phone numbers in the radio and everyone I take it out and put it back there not saved. Any ideas why

You have to make sure that you have a permanent live connected to the radio seperate to the ignition controlled supply. It should be detailed in the wiring instructions in the manual for the radio. Hope this helps.
