It wasn't my intention to be sarcastic.
I appreciate that my knowledge of GPS Software is limited but Mr canderson's attitude was less than helpful.
OK so I didn't buy the most expensive head unit on the market because I could not afford it and when I asked the supplier if the unit was receptive to Tom tom the answer was to the positive with the information given that it was receptive to Windows 6 OS.
Now if that isn't acceptable to Mr c then sobeit but there was no need to show his superiority on all things GPS and Tom tom by making snide remarks on my decision to purchase a unit that is fitted with iGO 8.
So if thats his altitude then he can stay up there

I asked for help not castigation!
Incidentally a friend on a SAAB site (my unit is fitted to my SAAB) who also has the same unit I have since found out fitted Tom tom software which works but wasn't impressed with as it only had a voice with an American accent. Sorry I am only saying what he said.
