my chinese gps works on 3 different port/baud rates but ONLY ONE works properly on all gps programs with no dropouts and correct info shown.
have you checked "auto" in gps settings and let igo find the port/baud itself? it was the way i found out that igo prefers port1/baud4800 not the baud11xxxx/port2 that is supposed to be the units default.
worth a try
