Hi,
I've been using Navcore 9.485 for a number of months.
Even though I have more free RAM (7 to 8MB) compared to when I was using 8.414 (4 to 5MB), the device has a tendency to re-boot. Sometimes it behaves itself, sometimes it doesn't. I never had any problems with 8.414.
I've got an XL30 (32MB) & use IQ routes & Loquendo and run in "XL" emulation.
Perhaps, there is a better emulation?
May be time to change my TT. I'm considering an XXL (2gb).
Wolfman.
