ok, before I ebay it I thought I'd offer it here:
Sony Ericsson P1i on O2, bought from carphonewarehouse, I dont know if it is unlocked as I have no way of checking. Fully boxed with all accessories (docking cradle, data cable, charger, spare stylus, manuals etc) and 1gb memory card. Had a screen protector on it since day one. about 6mths old.
Sony Ericsson HCA-60 Fitted Carkit, also comes with the HCE-26 Stereo Mute Box which will route the conversation through the car speakers. The HCE-26 also allows you to listen to phone-based music, in stereo, through the car speakers. With the HCE-26 fitted, there is no need to fit the mono speaker supplied with the HCA-60 kit, as all sound is routed through your car stereo.
Fully Boxed with fitting instructions, also about 6mth old. Cost me £150
The kit comes with the cradle for the P1i, but other cradles are available if you have or change to different phone.
The carkit is very good, I used it in a van which is quite noisy on the road, but the calls were very good, something which cant be said for some hands free.
I will sell as a complete set for £200
or the P1i for £160 and the carkit for £50
I'll try to get some pics up this weekend.
