I would stay as far away from TVonNAV as possible. I live one state away from them and I can not get them to send me the part I need, in motion module, its been only a year that I have been waiting for them to return the part that I sent them. I call them at least 3 times a month and leave them a very polite message. Have not heard anything and it's been almost a year now. You live in Ireland.. might take them 5 years for you to get yours.
