Sat Nav Keyring

[PicknMix]

Hi there,

Does anyone have any experience of sat nav keryrings that work in conjuction with your mobile or PDA via bluetooth??

I'm looking to buy one for a present for my husband and I'm not sure if its worth it or not.

I've worked out that it'll work with both his phone and his PDA so not worried about that, just more concerned as to whether they're any good or, in fact, actually work

Any advice gratefully accepted!!

Thanks

PnM
