I have a 2004 RX8 95k.

The navi screen comes on and shows map.

It also shows my location when I first start car.

When I drive no movement of my position.

I shut car off, restart car and navi restarts, it shows my location again, no movement etc.....

Any Help would be great.

Thanks all

Jeff

 

GPS antenna.

 

Would that be a guess or speaking from experience? Just want to be 100% sure before I try and find one to install.

 

Experience. You need to do a little trouble shooting, here's a link: http://foxed.ca/rx7manual/2003mazdarx8/ Look in the entertainment section.
