    Porsche's navigation system - DVD-based better than CD-based

    Is there really a big difference or improvement when moving to a DVD based navigation system such as what was offered in the 2005 Cayennes versus the 2004 version? Is it just that you have to 'load' more CD's when you go out of your region, whereas the DVD holds it all, or is the screen and/or output worse?

    The DVD based version is not only faster but it also has a better screen, even if it looks completely the same.
    There have been improvements, I would defintely prefer the DVD based version, unfortunately my car is a march 2004 build and I still have the CD version.

    Darn, because I'm wanting to get a CPO turbo, and the 2004's are a big bargain. I don't have any nav now, but my wife has a Lexus GX470 and she made me promise that my next 'daily driver' would have Nav. Will it compare to a 2004 Lexus GX470's system?

    I'm sorry, I don't know the GX470 system. And since I don't live in the US, I'm not sure if it helps if I tell you that over here in Europe, the Cayenne Nav system (CD based) is working pretty well.

    Re: Porsche's navigation system - DVD-based better than CD-b

    Despite no touch screen on the Porsche, the navigation system is much better than the Lexus one (RX model), simpler, clearer and much better graphics.

    Re: Porsche's navigation system - DVD-based better than CD-b

    SciFrog, are you talking about the CD-based Nav system, or the DVD based Nav system (for the Porsche)? How does the Porsche one work if there is no touch screen - buttons and toggles, as there is no voice command? Frankly, navigation systems annoy me and I would use it only once in a blue moon anyway. It's my wife who is totally addicted to them.

    Re: Porsche's navigation system - DVD-based better than CD-b

    CD based of the Cayenne and 996 (they are the same). Dunno about the DVD one. No voice activation but the system speaks to you of course. Also a simple direction chart shows up in you LCD display among your center dash dials, very cool.

    You use a rotating button to select the letters, the system is smart enough to give you only a letter choice that forms a word (town/street) in its database after the first character, so you don't have to toggle though all the letters.

    The graphics are great IMHO.

    Re: Porsche's navigation system - DVD-based better than CD-b

    Not sure how much this helps, since I don't know the Porsche CD system. I have the DVD version, and have had multiple versions of Nav in previous and current vehicles (incl. 2004 Lexus RX version, which I assume is similar to GX). The current Porsche system calculates routes faster, and recalculates much faster if you take a wrong turn. Its voice commands are more straightforward and give you more warning. The screens are similar, small edge to Porsche. The P system lets you do more while moving (more functions locked out for safety with the Lexus). HOWEVER, the lack of touch screen makes entering a destination a MUCH bigger PITA for the P system. Plus, most of the data entry is with the silly rotating knob, and the menu navigation is inconsistent (in some menus, clockwise moves your cursor down or forward, and in others, clockwise moves the cursor up).

    Neither system compares favorably to aftermarket systems (Kenwood, Pioneer) that I have owned or used that cost $2500 US or less and which were easier to program, had better screens, and lots of helpful display options, such as a semi-3D, distance-relational view.

    If you don't use it much, the P system will be fine.

    Re: Porsche's navigation system - DVD-based better than CD-based

    The CD based sytem was horrible. I bought a Cayenne S on the first day it was sold in the US. I have sold that car partially to my emotional reaction to the poor CD system in the US. I was use to the DVD systems in Lexus cars. I had a LS 430, a RX300 and a SC 430. All these had very stable navigation systems with excellent information built in. Each of these systems was slightly different, but simple and easily to use. You could drive down the road and listen to a audio CD and use the navigation sytem. On the Porsche CD navigation system without a CD multiplayer required you to swap the navigation CD with the audio CD. This was a pain in the tin can and I cracked my navigation CD which cost me several hundred dollars to replace. (The use of high performace summer tires on the first SUVs made me mad also.) I also have a BMW M3 with DVD navigation (non touch screen) and it works very well. When you ask people about which is best they will often tell you about what they have become use to. I will have my new 997 C4S within the next month and I ordered it with the DVD navigation system. I will NEVER buy a CD based system again. Very un-Porsche to use a second class system. It was a joke. DVD or nothing!

    Re: Porsche's navigation system - DVD-based better than CD-based

    Having used the BMW x5's Nav system for several years, I definitely prefer that to the Porsche's (been using for a year)...

    The BM gives you ample time to make the necessary turns (also using a very useful Meter / Feet distance countdown) whereas the P just tells you to make a 'next right' turn. If you are on a junction, it's very easy to miss your exit.

    I'm not a big fan of the P system at all.

    Re: Porsche's navigation system - DVD-based better than CD-b

    Hi,

    Another PITA is the recent upgrade to add post code searches and TMC (traffic management channel for real time re-routes based on traffic) is ONLY available for DVD based systems. My 18 month car will not be able to support functions available for over 3 years on BMW and Mercs.

    Road data for each region does vary, here in europe several countries fit on a single disk with most or western europe covered on 3 cd's. I can't comment on DVD. Quality of the road info is generally good with voice command prompts giving plenty of notice.

    On another point I just pickd up a very cheap (Pounds125!) pocketpc based system and when both were on in the car the voice prompts were excatly the same and happened at the same time!

    Lets be honest it may have been best of breed back in 2001 when it was designed but thiings have moved on and Porsche have not really kept up with what they buy in from Becker.

    Re: Porsche's navigation system - DVD-based better than CD-b

    Mish,

    I'm the opposite to you. I disliked the system in the X5 but find the dvd based Porsche system to be very good with plenty of advanced warning. I had an E60 5 series BMW with the professional widescreen display nav in the i-drive system and that is one of the best OEM fit systems I've personally used. It's high location of the dash was also much safer to read whilst driving than glancing down at the PCM unit in the Cayenne.

    I've had to order the 2006 update for the PCM in my car to get the TMC system activated. I'm really angry that I'm having to pay out Pounds420 for a new dvd disc - where do they get these prices from?? It will save me time though as nav without traffic updates on the congested roads of the UK is a nightmare.

    Re: Porsche's navigation system - DVD-based better than CD-b

    A big plus of the DVD based nav is that it can play mp3 CDs. That makes the CD changer obolete IMO.
