Faulty Tns700 Sat Nav

[big mally]

My satnav has recently been saying that it cannot read the disc properly. I took it out and it looks fine. I bought a brand new Toyota set of discs about a year back and it is perfectly clean. Also, when I first start the engine and press the ok button, this has started to sometimes freeze and then the map appears after about 10-15 seconds. Then about a few minutes later the screen goes black and it says that it is having problems reading the disc and that I should try to clean it. Wonder if there are problems with the system, rather than just the laser, since I am having problems getting the satnav fired up with the initial ok button.

Any thoughts/suggestions?

Is there no way of resetting the unit, or is that it? Any suggestions? Just seems a shame since I only bought the new nav discs about a year ago. I really loved the system and now it just sits there saying cannot read the dvd.

the cost of fixing them could be very dear, I'd try from a breakers, there is probably plenty around now, it's worth getting quote but fixing the old one may be to much,you will sell the discs no problem on eBay or here,i sold my car with it not working,my friend replaced his with a different aftermarket unit,pioneer I think,he said it was much better,good luck
