Hello, I had a few questions for you guys….. I am thinking of replacing my 99 GTP with a Bonneville GXP, I searched this forum but was unable to find the answer to my question; hopefully you guys can help out.

My major concern is that I want an in-dash HU that will work in this car that will have I-pod, XM, Bluetooth, and Nav. Is this possible and has anyone else done this mod? If I purchase a GXP I would like to have the HUD and Steering wheels controls still work, does anyone know if the interfaces that I believe PCM made for the Grand Prix work in this car?

Thanks,
Nick

I can't answer, but what did you have installed in your 99 GTP? I'm not really thinking of replacing the 'Monsoon' system in my GXP, but I'm curious. One of the things I like about the GXP I bought was it has both cassette tape and CD. Being an 'old fart' I have a lot of old cassettes that are in good shape and there'* too many to take the time to transfer them all to mp3 files.

yes there are options to get whatever headunit you wanted into your GXP. there are various modules that can retain all the factory functions.

One thing that you will not be able to retain is the radio info on the HUD
