Maybe it's worth taking your amp out and seeing if you can get it repaired, most can be fixed. If I could find a UK based company for an Android unit I would get one, I'm just a bit unsure of buying one from overseas and finding it doesn't fit.
I've looked at the possibility of getting one, if is was simply a plug and play system I may do it but there just isn't enough info out there. Either way you still need your amp to work.
