For the RF the entry-level model is the SE-L Nav (unlike the MX-5 Convertible that starts with the more rudimentary SE trim), which comes with a 7.0in colour screen, sat-nav, DAB radio and Bluetooth connectivity.
As well as being well equipped, the infotainment system is easily controlled via a rotary switch and shortcut buttons in front of the gearlever. The only irritation is that you can’t turn off voice guidance altogether – you can silence it, but it still dims the speakers when there would have been a guidance announcement.
The Bluetooth is quite effective – it’s easy to connect the phone, and it’s possible to hold a hands-free telephone conversation with the roof up on the motorway. Roof down, you will struggle, though. There are two USB connectors at the base of the dash, next to a cubby, making it an ideal place for storing and charging a mobile phone.
