Despite sunlight the display is easy to read, at night a bit too bright, you could darken with tinted film, but I did not need.
Heat makes him nothing, everything works perfectly, even the controls are continuous use after 7 months all ok.
Bluetooth handsfree (with Sony Ericsson K800i) and optional microphone with absolutely no problems, super comfortable on your car speakers, you need the phone no longer to take out of his pocket and no extra hands-free. After one connecting the mobile phone with the radio, the Bluetooth connection is established with the mobile phone automatically every time you start the car.
With 1 GB SD card infinitely more music, easy to plug.
USB port for memory stick, etc. (funtioniert properly), even the mobile phone or other devices can be loaded above.
The menu system is a bit complicated, but if you can deal with a modern mobile phone or PC, it has to get out quickly.
Radio reception is still ok, but the priorities are in this unit clearly with a variety of connectors (SD Card, USB), Bluetooth handsfree and the price.
Conclusion: ideal for convertible since no additional equipment is needed, all in one, reliable and inexpensive
