Maybe worth it.
If you are not planning on changing the radio for a better navigation system, go ahead, its a small price compared to installing another system.<br> I removed the navigation from my ML55 complete with the bose subwoofer, amplifier and speakers. I installed the new Kenwood DVD headunit and Kenwood navigation, Boston Pro 6.5 speakers in every door, Boston c210 Sub Box and Precision Power Amplifiers. My story is: I went to the dealer and they offered me the ML55 with no wait list, I drove it and loved it, one hour later I owned it, I changed the cd's from my car to the ML and decided to go for a drive and.............<br> The sound system dissapointed me so much that I almost wanted to take the car back, I can't believe that the BOSE system was so weak. I went ahead and with 300 miles changed the audio system, I am pleased to say that the Kenwood Navigation is far more uperior than the Alpine Mercedes.<br> So its your call, I would say that there is a difference in the two systems because of the BOSE subwoofer, thats about it.<br> Please email me if you want to ask me anything.<br> Good luck with your purchase.<br> JB<p>cache-2.sbo.ma.webcache.rcn.net
