I didnt fancy the idea of drilling holes into the dash either, and ive heard of devises on the market that slide down the side of the dash, but to be honest i just didnt fancy the thought of having the cradle on show spoiling the look of the interior.
So............. i went BLUETOOTH
Upgraded my Nokia to a 6310i all for £29.99
then bought the Nokia Bluetooth car kit CARK-112, with this kit you DONT need a cradle and you can place the mobile anywhere in the car :)
I wondered who to trust to fit it, and in the end fitted it myself (piece of P155). It only requires 3 wires to be connected and you are away :D
Its fabulisious, works a treat.
The fact that i installed it, i was able to do it so that ALL componets are very discreet, if you sat in the car you wouldnt even know it was there (even to the microphone) !
