Shot me I got to many Questions!!

What Navigation Bluetooth Device is supported with the Nokia N800 and 770??
I know Navicore make a device for the n800, but there are a lot cheaper ones at Amazon.com that are a off brand like,Deluo LLC, Holux M-1000 32, or the TomTom Bluetooth GPS! Let me know
I figure any Bluetooth Navigation device would work, but not sure. Thanks for whoever answers this one!!
