it aint that bad!
...
now the bose sound system on the other hand....
I've got the bose system with Nav (standard on Australia version of Grand Touring) and it was horrible! Some of the annoying bits:
1. "Auto" screen dim doesnt work, it still bright as heck in the middle of the nite on the highway (I dont want to risk changing it to "night dim mode" manually since I was traveling 120km/h)
2. You need to press more than 5 buttons to redial! ("Agree" button --> Menu --> Bluetooth Phone --> out goings --> The green call button (yes, you CANT click on the caller name to make a call)
3. No way you can call or access the phone menu from the steering wheels (all you can do is voice command) - I can do this on my other cars (Merc C200, Hyundai i30 and Honda Accord Euro/Acura TSX)
4. Phonebook on Voice command is different to the one stored on the Head Unit (Who needs two contact books? You should be able to sign a "voice name" to the contacts under your head unit, not create different list!)
5. Songs information from BT audio to my iphone 4 sometimes shown correctly, sometimes it shows the first song played and you cant click anything (random, repeat, menu, etc) are all disabled. Technician answer to this? Oh it probably because the songs are not in MP3/MP4 format. What the heck???
Anwyay, the navigation part itself is not bad (weird thing they have "Any City" button to allow the HU to pickup any city randomly and shown that as your destination... WTF??)... just the user friendliness is crap! I'm working in the industry where user friendliness is one of the most important thing, so sorry if I'm being to harsh here...
