hi all, was just wondering if there are many after market radios that are easily installed into the gp, that you can still use steering wheel controlls and also the blue and me?
Only the original stereo supports Blue and Me, you can get adaptors to enable use of the steering wheel controls for most of the major brands (Sony, Kenwood, JVC, Pioneer, etc).
thanks for that, if I'm just wanting to get better quality sound is it possible with the oem blaupunkt head unit and just get better speakers and tweeters, or does the head unit need upgrading too?
The headunit and standard speakers are designed to work together, you could upgrade the speakers and it might be slightly better but a better source will give a better output, so you're really better off changing the headunit too.
I have a sub fitted in my grande punto and im more than happy with the sound quality, as with the sub you dont need the bass through the original speakers so they can take a higher volume without distorting.
