Tom, in my case the navteq code is included with my GPSR but with adds.

When I entered the non ad version, it took the code but I still receive ads in the USA. The original ad versioned sub still works. Are you suggesting that one needs to add BOTH USA and Canada subs to get the non ad version?

Do you know how to remove the TTN/Clear Channel sub? It's the priority frequency and it only works kinda, monday to friday. it's pretty much useless in my area yet it is on a more powerful [channel] than navteq.
