Upgrading Stereo - Last Minute Advise Needed

[greg9ball]

Its finally time to upgrade my stereo. I have an 05 Boxster S with the Bose CDR24 unit. I am planning on replacing the head unit and amp.

I have decided on a Kenwood DVD Navigation system; however, I keep waffling on which one.

I initially decided on the DNX6140 as it is probably all I need. I have found it for $678 on Amazon. Then I noticed that I could get the DNX8120 for $999 (it is discontinued, but some are still available on the market.) I have also considered going with the DNX9140 for $1345.00.

Does anyone have experience with any of these units? I believe one of the big benefits of going from the DNX6140 to the higher end units is that it plays 5.1. Does the 5.1 sound work well with the Bose surround sound Speaker system? Is it worth the difference in cost?

I plan to go with the Alpine PDX-5 amp. I will be using the Kenwood KCA-IP301V ipod video direct cable.

Here are where I need some serious advice:

1. There is a local installer who comes highly recommended; however, he's never performed a Boxster installation. Is this an installation that a reasonably good installer can handle?

2. What other parts will be necessary for this installation.

3. Does anyone have any recommendations that I can give the installer to make this go smoothly and look excellent. I heard that there is some kit on Ebay, but I haven't been able to find it. Can anyone point me in the right direction?

4. Am I forgetting anything?

5. Is it worth going to the higher end units.

Thank you very much for your help!
