Skoda A5 questions

Hey guys

I don't know if this is the right place for the topic

so I am sorry if it is in the wrong place

I have a Skoda A5 model 2006 full options without parking sensors

and I was looking forward to tune it

any ideas or some one have done this before ?

I was thinking about changing the cassette player to mp3 player with the 6 CD changer ( Stock one ) .. and I was asking if the Fantazya cassette works on A5 ?

2- I was looking forward to add a stock sensors too ?

any comments will be accepted

Thanks in advance
