I have noticed with the Nav system, that my home is about 2 blocks or so off. The nice lady in my radio says, "you have arrived." Then we get into a bit of an argument, because I know exactly where my house is, and it is not 2 blocks (in either direction) from where I actually am. :shock:

I am now out of state on a business trip and the nice lady in my Nav system is off on my destination (about 2 blocks off again). If it weren’t for ‘POI’ search, I never would have found the hotel.

Is there any way to tweak the Avic-z1 so it knows my exact location?

Have you try to use the current position in the menu. I think that will allow you to adjust the current position on the map. I don't know it will help or not. I never had this probolem. Let me know is that help.

The manual says you're alerted within 300 meters (approx 2/10ths of a mile.)

pg. 62 of the user manual

When the location with a sound effect and an
image are registered comes into approx. 0.19
miles (300 m) radius from the vehicle position,
the sound effect plays and the image appears.

Thanks for the page info, I will check it out when I get back home...I didn't take the manual with me.

I am staying at the Marriott and I picked that in the POI functions. Why would that be off? I passed it on the other side of street (I got lucky and was looking that way) but it kept telling me to drive. I ended up about 1/2 mile (in a bad area) than where the hotel actually was.
