You need a VOR for the test. You will not get tested unless you have a clockwork VOR installed in your test aircraft, the skymap is not sufficient. As for the training you need to speak to Policy regarding this It is my opinion that the skymap is not acceptable for this
Please Please seek advice from the CAA before starting trainnig. If the aircraft has not been used for training by the FTO they will also need to fill in a form to ensure that it meets the minimum equipment levels to teach on approved courses, this form needs to be sent to their training inspector before the start of your course
