Help, air suspension, sunroof and NAV???

[H2Singh]

Thanks to the quick responses.

Still curious if an aftermarket NAV/stereo/DVD/CD/XM unit could use the controls on the steering wheel? has anyone tried it. The main advantage is that there are many aftermarket units that have bluetooth and I would love to use my stereo as a hands free. --- by the way thanks Klaus, that is a great link and solution to be able to have cd playing while using NAV with the stock RDS.

The dealer seems to be scaring me away from the air suspension, saying i don't need it, it will that the bags will go bad after a while b/c of lack of use and it will sit like those old lincolns use too, that it makes more noise, i just think it's cause he doesn't have any lux packages with the air.

Still wondering if anyone had problems with lack of space b/c of sunroof in the rear seat and if there is a way to get them slightly reclined, b/c there is a little more headroom available if they were reclined the bump in the ceiling ends just where my head hits now.

thanks again

off topic, what are the best ways to get more power out of this beast without voiding warranty???
