It seems Primo has a strange problem: when a route set, when entering a tunnel, Primo crashes and the GPS device restarts.
Especially Chinese WinCE 5.0 and 6.0 devices, with original 480x272 data.zip, with modified 320x240 and 400x240 data.zip, all are suffering. So all data.zip files are involved.

I can not confirm this because I have no Chinese device. Also, when road testing Primo, I did not pass a tunnel yet. I never even taken Primo on longer trips. But I guess the behavior of crashing in a tunnel may look familiar to some of you.

What to do and can it be solved?
Well, I hope. I got this tip: put in the sys.txt

[navigation]
use_duration_for_tunnel=1
stop_at_tunnel_end=1

[feature]
tunnel_guidance=0

I hope someone can confirm it helps.

I'm near some motorway tunnels that i go through a lot and i've not experienced this.

Like Captain Picard would say on Startrek - "make it so!"

With Chinese Din? Looking at your signature, it could be device related. Also the distance (length of the tunnel).
And hey,I know the road to my work without needing Primo

I don't have a chinese device, I also know my way to work But keep the nav on to warn me of the millions of speed cameras the UK have to put up with.

I ran an earlier Primo thru tunnels here in Oz with no issues other than I prefer igo8. (Primno removed)
800x480 , incar 2 din chinese all in one.
