Stereo Upgrade

[Lex Andrews]

I know this may seem a little odd. I have a RT4? Stereo in the C5. It has Bluetooth and a RCA port in the glove box. I have my Galaxy S4 connected to the Stereo via the RCA port if I want to play the MP3's from the phone.

What I'm asking is:

Can the stereo be changed for a upgraded unit? I know I may lose the Bluetooth if I change from the RT4. Can the RCA unit be changed to a USB box? Can the Display run the track data? I have a shark fin type ariel on the roof. I originally thought that the Sat Nav systems ran with this type of ariel setup.

Reason I'm asking this is at the moment when playing MP3's I have nowhere to sit the phone, without a cradle or mounting a cradle on the dash. When I had my 9-5 I attached a back case to the centre vent to hold the phone, connected that via a tape player to the stereo. Perfect position If a little crude looking when the phone wasn't attached. I have nowhere to put the phone on the C5 dash in a similar position.
