Sat Nav Help

[linz79]

Hi I'm just looking for some help with my sat nav,When I turn it on all it keeps saying is open + check CD Rom which I have done,But some1 suggested to me that it could be damp in the boot,and told me to try blowing inside it with a hairdryer and believe it or not it worked.I have even tried buying a new CD Rom disc but no look yet.Any1 help plz

Yes it can happen, the optical lens on the pickup laser can get condensation on it and cannot focus on the disc, a bit like if your glasses mist up.

snip...... and believe it or not it worked.

I thought it worked just like Steve too! :-)

There isn't a lot more you can do really other than look for a scrapper that might be being sold, or you can take yours apart and on some models on the mylar cable that moves with the laser head there is a tiny pot you can adjust the laser gain with. Try both ways as it isn't always clockwise to increase as you would expect. Be slow and keep trying as too much gain introduces focusing issues.

I'm afraid I don't know anywhere particularly but if you know any car audio shops they can usually put you in touch with decent engineers.
