No working radio, cigarette lighter and tachometer

[Gadgetman]

On mine, which looks pretty similar to the pictured one:
F1 = 10A: Radio
F2 = 5A: Speed sensor, Coolant for engine, Double relay injection(black lump controlling fuel pump on gasoline engines at least), coolant and catalyst warning light, diagnostics connector, headlight indictor on dashboard
F3 = 15A: ABS computer(on cars with ABS)
F4 = 5A: Lefthand front and righthand rear parking lights.
F5 = 5A: Relay driving lights.
F6 = 10A: Relay switch AC
F7 = 20A: Horn, diagnostics connector.
F8 - Shunt
F9 = 5A: Righthand front and lefthandd rear parking lights, license plate lights.
F10 = 20A: Window lift driver's side(lefthand side) + 'sequence box'(whatever that is?)
F11 = 20A Window lift passenger side.
F12 = 20A: Reversing light, 'start blocker' Diesel(?)
F13 = 5A: Switch driver's side window lift.
F14 = 10A: receiver remote control
F15 = 15A: central locking unit.
F16 = 15A: cigarette lighter.
F17 - Unused...
F18 = 5A: Rear foglights, warning light.
F19 = 5A: Lights instrument binnacle, switches, ashtray, radio**
F20 = 25A: Fan AC
F21= 5A: Switch AC, relay fan, relay heated seats, switch heated rear window, timer for heated rear window.
F22 = 20A: Motor rear wiper, timed front wiper.
F23 - Shunt - actually, it's only listed because of the F8 Shunt which is halfway into this slot.
F24 = 20A: Wiper front, motor front wiper.
F25 = 5A: Temperature box coolant, ECU, start blocker diesel, Roof lights front and rear, radio memory, clock
F26 = 15A: Switch emergency lights.
F27 = 30A Heated rear window, heated mirrors.
F28 = 15A: Electric mirror, timed front window wiper, relay window lift.
F29 = 30A: Cooliing fan AC or heated seats.
F30 = 10A: Mapreading light, blinkers, receiver remote, instrument binnacle.

* On a 'PRE BSI' model, the cental locking unit is a separate unit, placed in the side, behind the wall panel next to the lefthand rear passenger seat.

** The Radio usually have more than one supply line; one connected to the ignition, and one direct.

Some items have one fuse for 'ignition off' and another for 'ignition on' situations.
Also, the manual may not be for just one model.

You have a 10A fuse in slot F2, which is weird as it SHOULD have been a 5A fuse there.
I assume the 5A blew, and he did a 'quick and dirty' fix, by replacing it with the F1 fuse...
Which is weird as the 5 leftmost, unnumbered fuses are the spares, and there's a 5A fuse there.

What I fear is that there may be bigger problems somewhere, since replacing a fuse is a £0.1 fix, and can potentially change the value of the car quite a lot. (Didn't he watch Wheeler Dealers on Discovery channel?)
Also, this was a rather hurried translation from Norwegian manual which I worry may have been translated by someone with slightly less than 100% enthusiasm for good cars.
