Upgarde L322 RR Vogue 2003 Radio / Stereo / entertainment head unit

Dear all
I have a 2003 L322 Range Rover Vogue, one beautiful car. I would like to upgarde the entertainment system and would like some advice on what to but and where to get it from TV is old analogue TV, an original phone, a CD sytem that doesnt work and a pretty basic Sat Nav system
would love all the latest functionality, Digital TV, DVB Radio, Phone connectivity and Sat Nav (touch screen would be good)
ideas please ladies and gents? how much should i expect to pay? could anyone suggest a good audio shop / engineer
Thank you all very much for taking the time to read

if you use the search function there is quite a bit of info already on here from upgrading to digital tv to replacing the lot with android kit.
The mk3 satnav can be swapped out directly to the bmw mk4 DVD kit which is better
