Hi there - new member here with my first Merc - lovely but the radio finds it very hard to lock on to stations - I can just about get radio 2 if I stand one leg with my finger in my ear Anyhow, reading around I can confirm that the doors unlock from at least 10 m away, although the boot needs the key to be nearby. Fuses are OK as far as I can tell. I would use one of those bluetooth thingys for the phone except that the radio won't lock on in the first place. Quite happy to get an Android unit or whatever, but when it works the radio is excellent so I would rather keep it. CD is fine. Would appreciate any thoughts - BTW - there is no tinting on the rear window.
