I bought this for the nav and ipod functions both are sketchy at best. The nav is not very professional looking it looks like someone designed it in their garage. Every time I hook my phone up it takes about 10 minutes for the radio to stop playing static and start playing music. Considering it was a little more than $300 bucks compared to the $900 for a decent system, it works okay. If I had to do it all over again I would have waited until I had more money. For a company truck it works.
