I have a Second Sportrack pro the I just picked up for a good price,(my old one got wet)
I also have a Sportrack Colour, but Discoveraus wont let me upload maps to the new addition as it has alredy got the previous 2 Units in a file somewhere.
Is there any way I can add the new unit?

I suggest you let Next Destination know and you may have to send back the "dead" GPS and they in turn will give you a new unlock. Let me know how it goes if you do.

Only way to add another unit that I know is to uninstall and re-install DAST.

Of course this will only allow mapping for two units again.
