Good morning, I'm having problems in the IFR approach, I use the gn 530 native of the bell 429, I enter the procedure, leg of the wind, more inves to get to the base leg the 429 turns to the left, does anyone know what I can do? Does reality xp solve my problem?

Are you asking about the default XP11 GNS530 making procedure turns?  In my experience the default does not always work.  RXP unit will command the correct turn and tell you when to turn.

Dude, I bought the GTN750 and it still has the same flaw.

I'm not exactly sure what your question is... are you hand flying this?  What approach is it and where are you approaching the IAF from?  Both my GNS and GTN's will display the proper HiLPT or PT or hold etc.
