It sounds like my indicators sound comes from behind the radio. I got a speaker with mine thsts connected and behind the radio so I think they are coming from that.So I had a delivery just after lunch today. Just as Homeofthejack the unit is simple to install. I installed the GPS unit up on the dash where the centre speaker lives - I was out to pick my daughter up from school at 3pm! Sorry no pictures....
Mine came with a lovely white Mondeo on the home screen and buggered around in the menus and managed to change it to an Astra.
Everything comes in km/h as previously said, again I found the setting to change this but the homescreen speedo then shows in increments of 18.6mph rather than recalibrating to decent mph increments so I changed this back.
The door opening icon was also wrong but playing deep in the settings rectified this.
Strangely my indicators and warning noises now do not exist - I haven't figured this one out yet....
The radio is FM and I am going to purchase the USB dongle to use DAB+. The climate controls are across the bottom of my screen all the time, you can turn these off in the settings if you wish and it shows the time/day/date instead.
I would be interested to see what settings Homeofthejack has on his unit as a comparison.
