hi guys, need some sat nav help of my own.

have fitted a becker sat nav din size cd based unit but cant get it to behave.

plugged in gps aerial and have connected up reversing light sensor and speed pulse sensor.

Have tried this bit twice so read from it what you will.

when I first connected it up I was in leeds. I set my destination and waited the ages it took to calculate a route, it told me my current position and what I should do.

at this point nothing else happened, it was not aware that I was moving. the road I was on remained the same (was correct when it found it) and the instructions did not change. when I checked current position (gps coordinates) it did appear to be changing. I gave up and listened to music instead.


next time I tried it was recently. I removed the unit and checked the speed pulse wire connection as I thought it was not getting a signal and therefore assumed I was stationery. the connections were fine. I input my destination and again waited the age it required. It then told me exactly where I was and what I should do, but once again, my current street address did not change, nor was I getting any nearer to the point at which I should turn left or whatever. This time when checking my current gps coordinates, it did not appear to be changing.

I bouht the unit second hand for £250 and it is an excellent cd player so am not completely bothered, but since it came out of a mercedes or something, it isnt a recognised normally available product and I wouldnt know who to talk to to suggest how I migth resolve the issue.

am not entirely fussed as I have dvd pioneer sat nav to go in the scoob, but since I do most of the travelling in this car, I thought it might be nice to get it working.

My thoughts are it could be a dodgy gps antenna. although it worked initially to work out where I was at the beginning, it doesnt appear to be changing after that, so maybe the unit was lucky to get one reading from it and is struggling to get another?

I seem to remember last time that it was at any one point telling me that it could see 6 satellites so I presumed it was working fine.

Any other ideas people?

ps. car is a corrado!

 

Adam, I think it's got to be a knackered GPS aerial. Where did you physically seat it? Might be worth re-seating to somewhere that has a clearer shot at the sky?
