Sorry to drag this back up, but I have only just got round to doing the 1300 upgrade as I have problems with burning media that the RNS would accept. And I thought I would finish off the 1300 topic with some info on the Skoda UHV BT module.
I was previously on 1100 and had reasonable operation of everything on the RNS but a wish to use V7 maps with full postcode has forced me to update, I eventually want to change the canbus but not yet.
First impressions of 1300 is a definite improvement in unit response noticeably faster in every operation including startup, unit also now displays speed limit for current road. Both are very worthwhile and I havent tried SDHC cards yet but that will be a major improvement to be able to quickly manage the music and extend capacity if needed.
Bluetooth - I have the Skoda 729B unit and previously had full operation with my HTC HD2 giving me 6 favorites on the phone screen, access to my phone book but only with access to my dialled number list, and no ability to voice call.
After update to 1300 I now have no favorites on the phone screen this area is blank, I have no access to the phone book yet I know have full access to the dialled missed and received call numbers including names and type of contact (home mobile office) and it will now give me access to voice dialling but the voice dialling still doesnt recognise my address book. The interesting thing is once you dial a number the name from the phone becomes associated with the number I have manually inputted!!!
All in all the update has been positive, I now just need to give it some time to check battery drain and SDHC. I will have to do some research into the bluetooth module but I believe its a known issue with the newer firmware versions.
