Pioneer avic-d3 or ???

[quebecduf]

Hi, I am looking to replace my radio in my 2002 BoxsterS. After looking everywhere on internet and Boxster forum, I decided to go with the Pioneer Avic- d3. So I purchased the installation kit and I am ready now to purchase the system. But ... reading the review i found out that the principal problem with the d3 is the fact that the CD need to be in the reader for the GPS . So you can't use GPS and Cd in the same time. Other than for going where you program to go. Ok Ok My question is, is there an other pioneer ( since I bought the instal kit ) that is a better solution than the D3 ???

Thank's
