I purchased this product as a replacement for my Tom TOM Go300.
It came on time however once plugged in, started crackling witha burning smell and then switched off. I complained and was sent a replacement, however I have since found that the product was not the correct voltage for my tom tom and burnt the IC switch inside.
This means my TOm Tom no longer works and I am left to decide whether to gamble on having it repaired (£40 plus postage if it can be repaired) or buying a new one.
The time, stress and extra finance this has cost has not been worth it!!! I would not take the chance but spend the extra £10 and buy an original/official tom tom accessory!
