Auto-on Sat Nav?

[AlanQ]

Are there any sat nav systems which just come on and start working as soon as they get power? I’ve used both Tomtom & Garmin before and good as they are they still require you to switch on, click through all the disclaimer rubbish and then actually program a destination. What I really want is something that can be wired to always power up with the ignition, display my current position and make a noise only if a speed cam POI is coming up. Like a snooper but with the nav display if you see what I mean. Does anyone know of any systems that work or can be made to work like this?

OK, thanks. Could’ve sworn the last ones I tried (borrowed) just sat forever on the disclaimer screen. Guess I wasn’t patient enough!
