aftermarket radio security feature ?

[lozz]

Fitted an Aftermarket radio in my d9 the other day,
had to swap the wires round as it wouidnt hold memmory,

Now ive got Another problem,
if i dont turn the Radio off before switching the ign off as Soon as The drivers door is opend it will Wake up the radio,
Had Prodigy blasting out at 4am the other morning its a good job ive no Neighbours that Moan

it seems the Bsi is still linked its self up with the Aftermarket radio is there away round this other than running a Seprate live -feed im lost,

any ideas ?

ive had another look
seems the Bsi is still looped,
if ileave the radio on with no ign- its doing the same thing as it did with the standard one Economy Mode Active!
im not going to play with the wiring not worth the Risk of Frying the Bsi,
