If you order a stereo system insist on one with a remote control.Very important. I don't have a fruit phone but our stereo has a USB port and an auxiliary audio input. I have a very small USB Flash Drive that holds hundreds of songs pluged into ours. They cost so little you can have one for every type of music you like. If I want to I can plug in an MP3 player or my Android phone but it's not worth the effort when I have the USB drive plugged in almost permanently.
Worth while considering the centre console trinket box. It sits between the seats just behind the gearbox hump. Handy for small objects and the remote control
Regarding mirrors: we ordered ours with round mirrors and a chrome (windscreen mounted) rearview mirror. One of the mirrors gave a greatly magnified view which was limited to a narrow field of view. I quickly had it swapped for a flat mirror. The offside mirror arm has to be brought in close to the body to be of any use. I will probably replace both mirrors in the not too distant future.
