Arno,

Just curious - how much did that entire system cost you?

Which radar do you have? We have the Navnet VX2 so perhaps our radar is older and won't work with the TZ2.

Ours works reasonably well aside from GPS rollover bugs (ha!) and I'm loathe to upgrade since you confirmed what I feared: "But it was a lot of work installing it all."
