Garmin 54LM?

Taken on two 'loop routes' stuck in left turns.
Taken around the long way even though quickest route selected.
Freeze on the display around 10mls in to journey with start point showing, magenta line showing but no car symbol showing. I am fed up with being fobbed off by Garmin saying down load this or that software. I have just updated my maps and there were also some software to download too so did the lot hopefully it may iron out my issues except the way points
Thanks for reading anyone with an idea if its a temp glitch on the freezing, will be helpful to know its not beginning to completely break down now its out of warranty.
