It`s called an BT77 BLUETOOTH GPS RECEIVER , I cannot give you a link as i dont have enough posts.

If not what would you suggest.

thankyou.

Is this the one?
GPS-BT77 GPS Bluetooth Receiver -- NaviGadget

I don't know about that one.

I can tell you that MANY here have used and highly recommended the Freedom Mini Keychain GPS, and you will find many people here who will help you with it should have have questions.

Hi.

Yes it`s that one, it`s very cheap , I dont want to spend much money on something i might only use a few times.

The one you linked is about £45 , bit too expensive.

So i need to know if this one works with the 8120.

any help is appreciated

Thankyou.
