Hi. I'm looking to buy the Freedom Keychain 2000 and I would just like to know how accurate it is? I currently have the Bluenext 51 channel receiver and it works quite well when exposed to the sky. I sometimes experience a delay in updates to my journey when the receiver is in my jacket and I have to take it out for it to establish a good signal. I thought the Keychain 2000 will take care of this issue as it's exposed to the sky at all times when walking. Does anyone know how much the Freedom Keychain 2000 is? and who sells them. Talknav did sell them but they have moved on to the 66 channel receiver. This wouldn't be ideal as the receiver would be kept in my pocket and I'd probably be facing the same problems once the receiver was placed in my pocket. If someone has the latest and greatest 66 channel receiver then perhaps they would like to give me some feed back on it.
