For those with TMC problems:
I have a 3300max wich came with ver 7.4.1 preinstalled.
I've installed this ver (7.4.2), and TMC didn't work for me either.
After a lot of try'n-error with different ports and whatso, I finnaly got it working!
-At first the TMC icon was greyet out
Got it working by using the original "tmchal.dll" that came preinstalled.
When that was set, and i could go into the TMC settings, TMC would't scan for any stations, just 3 dots.
Then I saw a folder that was in my preinstalled ver. and not in this 7.4.2 ver, Its called "AmarylloDynamics" and it contained a file called
"Adynamics.dll". Puting this folder/file in 7.4.2 made my TMC to scan for Fq.
Maybe som driver for the TMC chip
Anyway, after seeing that many have probs with TMC, i thought this may help.
Also, I got Panoramaview to work, but it did slow the system a bit.
Is that normal? or do i have to find a terrain file that is compatible with my system?
