A while ago Carphone Warehouse were advertising a £40 satnav accessory for the Sony Ericsson K800i. I believe that you needed to download some free software (nav4u or something similar). Anyway, I asked about it today at my local Carphone Warehouse and they said that it had been withdrawn. I was rather amused by the honest, but cynical, attitude of the sales person who, when I asked why it was withdrawn, replied that he didn't know as the management never told them anything. 
Anyway, does anyone know why it was withdrawn? Is it simply that it didn't work properly? I've got to admit that any product that relies on you downloading free software from a third party should probably be treated with suspicion.
There seem to be a few Internet sites that sell similar products. Are there any views on satnavs used with mobiles?
