Got a 2010 Porsche Boxster 987 Gen 2. 2.9 PDK with PCM3.0. The PCM unit is shows "loading maps... " Other functions of PCM like phone, radio, ipod etc works OK. Has been working OK for years previously.

Tried removing fuse row C F10 PCM3 TRM30. leaving out for 2mins to PCM unit, no difference.

Suspect the sat nav is a hard disk unit, not sure how this can be diagnosed or removed for repair or can a new map be loaded.

Very likely to be made by Becker. May be an idea to contact one of the Porsche Indy repairers. I’m sure they’ll have a contact for an effective repair. Have you tried a complete battery disconnect, rather than pulling fuses ?

Yes have tried a complete battery disconnect for about a minute. Having removed the fuse for alarm during this time.

Currently asking a couple of Porsche specialists and the Local Porsche dealer but thought I’d try this forum aswell.

Thanks for the response.

Its a Harman-Becker unit and they do go faulty. Its an old piece of hardware now. I think they used a 40GB HDD and they eventually go kaputt.

Best bet is to contact a specialist repairer of these German-made units. I don't want to give phone numbers or weblinks but if you do a search using the terms 'RNS-X-RAY' and 'West Bromwich' you should come up with the phone number of a company that can help you.
