Gps system for a Tungsten " T "

Hi every one ,I just bought a Tungsten "T" it has Mapopolis loaded 
into it. I also bought a HOLUX GR 236 GPS USB BlUETOOTH RECEIVER to 
use with my palm ,but I just can't get the the program,palm nor the 
gps to comunicate with each other !!! I want to buy the TOMTOM 6 
software but they do not suport the "T"! Has anyone installed this 
software on there "T" with good results. I was also want to try  
Delorme's Street Atlas 7 ... can anyone give me some advice!
