Sony HU not retaining memory ?

[The Big Yin]

Fitted this into the fb's car Pug 107 using the atandard ISO plugs but it does not retain any of the preset radio stations or retain her bluetooth connections - Im thinking of just running a permanent feed to the HU from the hazards but am unsure which connector on the block to wire them through any one had the same problem and know how best to get round it - she has chucked out the wiring diagram

Hu is a Sony MEX-BT2500

Cheers

try swapping the red and yellow wires around, they should have bullet connectors in the h/u loom. Had this many times
