thanks Burg Boxster,
the unit i have is the original PCM unit with inbuilt sat nav, phone sims, cassette, & a cd changer in the front boot, this is the PCM 2.1 newer version,

i noticed yesterday whilst the sun shone on the sat nav it is actually working but can only be seen with strong sunight on it, the cassette & cd however do not work, i am now wondering weather to take the old PCM out & fit a modern inbuilt sat nav/dvd player rather than paying to have the old unit looked at/repaired, any ideas which sat nav will fit good & sit flat in the dash,
