    Question Upgrading sotfware for a -02 navi

    Hi

    I'm wondering if I can use the service update CD with GM part. no. 19115256 for my -02 Delphi (Denso) DVD-based stock navigation unit or do I have to use another one?
    The reason I ask is that since this car is sold in Europe I have the RPO code
    U3S.
    Your domestic ones have the RPO code U3R or U3Q.

    Any info would be appreciated since the dealers here in Sweden hasn't got a clue..

    Re: Upgrading sotfware for a -02 navi

    why update it?
    the software update was only used in the event a power flux or the user accidentally flashed the hard drive...
    you gain no new features or options with the update

    Re: Upgrading sotfware for a -02 navi

    The reason I want to update it is because a service bullletin from Cadillac and Corvette Europe says that vehicles older than -07 must be updated in order to use navigation maps from -07 and newer...

    Re: Upgrading sotfware for a -02 navi

    The question I really need an answer to is if it's going to hurt anything if I choose to upgrade the firmware...I was thinking U3S with different options than your domestic ones can go bad if I choose the wrong update CD.
    Or is it just one for all three RPO:s..the U3S, U3Q and U3R?

    Re: Upgrading sotfware for a -02 navi

    Ohhhh...
    hummm
    the problem lies in the fact that p/n is discontinued and probably will not be found anywhere
    i have a copy of the disc along with the upload instructions and have used it to flash bricked navs but idk about a UK nav if it was Japan id say sure but the euro nav had the different am/fm band tuner frequencies....

    your BEST bet is to pull your nav
    the instructions i have state the software can ONLY be sure to flash navs with these part numbers
    25734875
    25743430
    25744040
    25755059
    25764007
    if your navs GM part number matches any of them

    Re: Upgrading sotfware for a -02 navi

    Ok, I already have a copy of the disc on it's way home
    But I was hoping not to pull the unit since I don't want to scratch or break anything..

    How do I remove the unit? If I can just get the top plastic of in one piece then the rest will hopefully be obvious.

    Re: Upgrading sotfware for a -02 navi

    Besides the radio frequencies are there any other risks? In that case I'm willing to give it a try since I don't use the radio that much...

    Re: Upgrading sotfware for a -02 navi

    Ok. I pulled the unit and wrote down the part. no.
    Gm no. is 25740478
    Denso no. is 462200-8032

    So it seems that this software update is not suitable for my system..
    There must be updates since they are selling maps for my STS..
    I checked and according to the TSB i have from Cadillac & Corvette Europe
    the same maps are used in STS 02-04. SRX 04-06, XLR 04-07.
    But of course they don't know what I'm atalking about..

    Re: Upgrading sotfware for a -02 navi

    have you tried asking a dealer about what is needed to do the update?
    also could try and contact GM Europe for intel

    Re: Upgrading sotfware for a -02 navi

    Some dealers says that it is not possible to use a map newer than 04, this is because the main parts importer/distributor for GM says it can't be done.
    They have interpreted the column in the TSB that says Seville MY02-04
    with February 2004 for road map data....I know since I tried to tell them that there are maps for 2007 and 2008 out. They tell me I'm wrong but still I have a 2007 road map disc right here.
    Others says that it can be done but they never manage to get info about the updates...
    I've tried Cadillac Sweden with no luck and when I tried Cadillac & Corvette Europe they referred me back to a dealer.
    I've tried most of the dealer in the souther and middle parts of Sweden...they either don't know or tell me that there are no maps newer than 2004 to my car...funny since I have the part. no right here for a 2008 map to a 2002 STS..

    Do you think it's done via a Tech2?

    Re: Upgrading sotfware for a -02 navi

    def not done via tech II
    Denso radios can only be serviced by Denso Japan hence why there are software updates via disc
    is you car under warranty still?

    Re: Upgrading sotfware for a -02 navi

    No warranty..
    Hmm, did I say that I've been in contact with gmnavdisc? They told me that Cadillac had the information not them..but when I read TSB:s they all refer back to gmnavdisc.com..
    Should I contact Denso?
